TAQOZ - Tachyon Forth for the P2 BOOT ROM

11718202223

Comments

  • Peter,

    On my P2-ES board, I am trying to see VGA output from the SD boot version (1.1) of TAQOZ. I can see VGA output from Cordic Crickets and Invaders demos. I have the Parallax VGA-PS2 Adapter Board. I have connected:

    P0 - hSync
    P1 - B0
    P2 - R0
    P3 - G0
    P4 - vSync
    VSS - Gnd

    Maybe I am assuming too much. I assumed that VGA would mirror what I am seeing on the TerraTerm window. Do I need the keyboard installed to run TAQOZ 1.1 on my VGA monitor? Sorry if this is a really basic question....

    TESTING & FORMATTING SD CARDS

    Prior to implementing SD FORMATTING in TAQOZ I have been looking at reporting card and format information. Even though there are a few little bugs in there such CHS and some CSD info, this is the report style I have at present. Hopefully I should be able to implement FORMAT soon which I will end up testing on a 64GB Sandisk. Besides default values the user will be able to specify partitions and cluster sizes etc.

    Other reporting utilities will show the sector map (where there are blank or used sectors or clusters or larger groups of sectors) etc.
    The CID also reports the manufacturer if known but at least the information that is recorded by the manufacturer, valid or invalid . I will also expand on the OCR and some more reports on actual read/write speeds.

    I will make up a connector for the ES board and double-check this myself. Have you tried to fault-find it yourself? Is that one of the new adapter pcbs?
    BTW - P0..P4 = HSYN,BLUE,GREEN,RED,VSYN

    Some further testing of my SD card reporting software where I check actual read speeds and report back for single sector reads and I also do a 256kB read and calculate the read speed for blocks mode. I used a Sandisk 64GB Ultra. Have a look at the results for a modest 180MHz clock rate.
    TAQOZ# .SPEEDS 
        SECTOR READ SPEEDS.............. 512us,516us,448us,449us,449us,449us,449us,449us,
        BLOCK READ RATE................. 7,426,565bytes/second @180MHz ok
    

    I think there must be an error there but I have clocked over 3MB/s before. Oh well, just testing the testing software!

    EDIT: I knew I made a miscalculation. This is the correct figure (for 8GB Sandisk Ultra):
        SECTOR READ SPEEDS.............. 514us,521us,449us,449us,449us,449us,449us,449us,
        BLOCK READ RATE................. 1,855kB/second @180MHz
    
        SECTOR READ SPEEDS.............. 392us,395us,327us,328us,328us,327us,328us,327us,
        BLOCK READ RATE................. 3,293kB/second @320MHz
    

    Interestingly, the 64GB Sandisk Ultra has a much longer latency on sector reads:
    SECTOR READ SPEEDS.............. 896us,927us,928us,926us,928us,930us,930us,927us,
        BLOCK READ RATE................. 1,847kB/second @180MHz

    I tweaked the SPI routines so that SD read speed is now 2.28MB/s @180MHz which is very close to the 25MHz SPI bus maximum for these cards. Has anyone tried using the Smart Pins in SPI mode?

    this sounds like your HW setup is working except maybe for
    BTW - P0..P4 = HSYN,BLUE,GREEN,RED,VSYN
    green and red switched

    but if your question is how to get the Taqos console redirected to output on VGA then try this:
    VGA  ." VGA" CON ." Console"
    
    VGA should redirect all standard output to VGA and CON will restore to the serial console
  • Hi Peter,

    Finally managed to boot TAQOZ v1.1, and it looks much better than the version that is burned into the ES. However, the output frequency is still not correct. For instance: 58 PIN 100 KHZ makes the pin output a 225KHz square wave.

    I guess the difference here is, TAQOZ v1.0 uses RCFAST, while this new version uses some frequency derived from the crystal. The new TAQOZ is "set" way too fast.

    Kind regards, Samuel Lourenço

    Thanks for letting me know and it is so. Seems that I had a hard constant in there from the FPGA version so I will fix that to work with the current clock setting and update the images.


    btw - you can try using this code:
    : NCOCNT ( hz -- cntval )	CLKHZ SWAP U/ 0 1 ROT UM// DROP NIP ;
    : MHZ				1000 *
    : KHZ				1000 *
    : HZ				NCOCNT
    : NCO				%1_00110
    : SETNCO ( val mode --)		2* L WRPIN 1 WXPIN WYPIN ;

    No, but thanks for reminding me. I might have a quick look at it and post some code back shortly.

    Hi Peter,

    Finally managed to boot TAQOZ v1.1, and it looks much better than the version that is burned into the ES. However, the output frequency is still not correct. For instance: 58 PIN 100 KHZ makes the pin output a 225KHz square wave.

    I guess the difference here is, TAQOZ v1.0 uses RCFAST, while this new version uses some frequency derived from the crystal. The new TAQOZ is "set" way too fast.

    Kind regards, Samuel Lourenço

    Thanks for letting me know and it is so. Seems that I had a hard constant in there from the FPGA version so I will fix that to work with the current clock setting and update the images.


    btw - you can try using this code:
    : NCOCNT ( hz -- cntval )	CLKHZ SWAP U/ 0 1 ROT UM// DROP NIP ;
    : MHZ				1000 *
    : KHZ				1000 *
    : HZ				NCOCNT
    : NCO				%1_00110
    : SETNCO ( val mode --)		2* L WRPIN 1 WXPIN WYPIN ;
    
    Thanks, Peter. That worked!

    By any chance, is it possible to implement baud rate correction on frequency change? The serial terminal will get unresponsive once I try ECO, SLOW, TURBO, etc.

    Kind regards, Samuel Lourenço

    Samuel,

    It should already be included, by default it corrects to 115200, but you can change that as shown here:

    Peter,

    On my P2-ES board, I am trying to see VGA output from the SD boot version (1.1) of TAQOZ. I can see VGA output from Cordic Crickets and Invaders demos. I have the Parallax VGA-PS2 Adapter Board. I have connected:

    P0 - hSync
    P1 - B0
    P2 - R0 G0
    P3 - G0 R0
    P4 - vSync
    VSS - Gnd

    Maybe I am assuming too much. I assumed that VGA would mirror what I am seeing on the TerraTerm window. Do I need the keyboard installed to run TAQOZ 1.1 on my VGA monitor? Sorry if this is a really basic question....

    this sounds like your HW setup is working except maybe for
    BTW - P0..P4 = HSYN,BLUE,GREEN,RED,VSYN
    green and red switched

    but if your question is how to get the Taqos console redirected to output on VGA then try this:
    VGA  ." VGA" CON ." Console"
    
    VGA should redirect all standard output to VGA and CON will restore to the serial console

    I mis-typed my configuration. Corrected above. It does match the correct hookups. I still can't get VGA output from TAQOZ. Do I need a PS/2 keyboard connected? I'm trying to see on VGA the same output as on TeraTerm...
  • I just checked the config and nothing was coming up but when I went to view a BMP file it sprang to life. Try 100 INT C! to set the intensity which may be sitting at zero. P2PC will run the serial console and VGA and keyboard if connected, in parallel.

    THERE IT IS! P2PC did the trick. I now see console output on the VGA screen.

    Thanks!

    P2-ES V2 BOOT IMAGE (updated link)

    For anyone who wants to have a play, I have a new V2 boot image. The new V2 kernel is a minimal precompiled kernel with most of the higher level functions metacompiled (pasting source to TAQOZ).

    There is quite a bit of stuff in there for reporting the SD and file system which you can access all in one go with .DISK or individually with .SD or .CARD or .FAT or further still with .PARTS .CID .CSD .OCR etc.

    This version will soon have proper SD formatter and disk utilities available and in fact I patched the partition table of one of my corrupted cards without losing anything. I also have an assembler to include yet and some I2C routines etc. I still need to fix a couple of minor issues with the SD report since I got caught off-guard using V1 of the CSD table rather than V2.

    You can make a boot file using the BACKUP word followed by the file name or BIX for a shortcut or else FLASH to save to the serial Flash (still needs a first stage boot program).

    In between everything I am filling in little gaps. Here's one that sets the pin drive modes where I have an LED connected to ground without any resistor.
    TAQOZ# 40 PIN   1ma SOURCE   OPEN DRAIN   5 HZ  ok
    
    What does it do? Just read from left to right "40 PIN ---- 1ma SOURCE --- OPEN DRAIN" selects P40 for 1ma source current with an open drain (float). (MISTAKE BTW)

    The pin drive modes take effect when we apply a function such as HZ or PWM etc and in this case it blinks 5 times a second.

    Then "100 1000 1 PWM" sets the pin to 10% (100:1000) duty-cycle PWM with a prescale of 1. So the LED is very dim.
    TAQOZ# 40 PIN   1K5 SOURCE   FAST SINK   100 1000 1 PWM  ok
    

    Then we change to 50% duty.
    TAQOZ# 500 1000 1 PWM  ok
    

    Next up I will turn the pin into an analog input and measure the surrounding light levels after which I will put it into touch sense mode by pulsing and reading the LED.

    EDIT: backing up all my changes to the SD boot file.

  • Peter,
    Could you please explain how "1ma SOURCE" works to actually limit the current through the pin?

    Thanks
    Tom
  • You just use different gate dimensions to set the channel resistance in a VLSI FET. Presume there's
    just a set of FETs in parallel to drive the pin, separately enabled.
  • If only we had a TAQOZ TEAM - to help fill in the gaps and build apps.

    Count me in Peter!

    1) I suggest that we create a TAQOZ repository on https://github.com/parallaxinc/ so that people who want to contribute code and docs and fix errors could make pull requests. It would just be a matter of creating a repo from your dropbox folder and converting the doc to markdown.

    2) I started making a driver for a Nokia 5110 LCD. Your current SPI driver is too fast at 180MHz for the LCD, I had to set the clock speed at SLOW (40 MHz) to make it work. What would you suggest? Making a second SPI driver in Forth with adjustable speed?

    3) For the Nokia 5110, there is a font I need to put in memory. Each character is 5 bytes. What is the best way to initialize an array in memory with Forth?

    I saw the code below but I don't quite understand the [C] and GRAB.
    CREATE FONT5X7
    $60 7 * ALLOT
    FONT5X7 $60 7 * ERASE

    	 0 OVER 5 ADO 2* I C@ 1 AND OR LOOP ( adr str val )
    	 3RD C! ( adr str ) 5 + SWAP 1+ SWAP
    	NEXT
    	2DROP
    	;
    
    "  00000000000000000000000000000000000" $20 ,,
    "  00100001000010000100001000000000100" $21 ,,
    "  01010010100101000000000000000000000" $22 ,,
    


    I also tried to test the TABLE word, but it does not seem to work with TAQOZ? (it fails after the second |)
    TABLE #bits	0 | 1 | 1 | 2 | 1 | 2 | 2 | 3 | 0 | 1 | 1 | 2 | 1 | 2 | 2 | 3 |
    
  • P2-ES V2 BOOT IMAGE (updated link)

    For anyone who wants to have a play, I have a new V2 boot image. The new V2 kernel is a minimal precompiled kernel with most of the higher level functions metacompiled (pasting source to TAQOZ).
    Tried 2 SD cards with the same result (boots up, runs TAQOZ V2, but does not allow accessing the file system of the SD card)... The SD cards were formatted as MS-DOS (FAT) on my macOS system. This formatting has worked in the past on V1.0 (see below). MOUNT, BACKUP BIX & DIR give "ERROR - INVALID PARTITION" errors, but .DISK does respond

    There are different hardware pin modes in P2, some with softer drive designed for saving a resistor.
    The 1mA is nominal, and will follow a usual MOSFET load line.
    260px-IvsV_mosfet.svg.png

    that will also vary with temperature and process.
    I've not seen a P2 load line plot yet ?

    Tried 2-32GB cards. One formatted with SD.org format suggested software, and one with Win10 formatter, FAT32. As @dgately found, both would not MOUNT and DIR. They both report FAT16 under TAQOS.
    Both woked fine under VER1.1.

    Under Ver2.0. a xx BLINK turns on the LED. I does not blink.

    EDIT:All test are on the P2 Eval board. Peter, do you have an EVAL board?

  • Ok - re the SD mounting issues. I've always been worried about the maximum clock speed I can use on the ES board due to the very long traces and capacitance. I tried another plain Sandisk 4GB card and it wouldn't mount properly. So I changed the P2 clock rate to 120MHz instead of 180MHz and now it works fine but no directory. However that is because it had no directory and whichever way it was formatted, it didn't even have an OEM or volume name. So I should at least report *empty directory" I guess.

    I then put some files onto the card and did another MOUNT at 120MHz with the result posted below. This is an older non-Ultra card manufactured in 2010.

    Now I have to think about how to handle SD cards on the ES with the extra capacitance. My P2D2 I can run at 240MHz comfortably without extra cooling and the SD card works fine.

    I got the exact same card that wasn't running properly on the ES until I dropped the clock to 120MHz, but ran it on the P2D2 at 240MHz without any problems. Argghhh. Now I have do a kludge just for the ES to slow it down.

  • Thanks for the update Peter.

  • Hi Peter,

    Now I've noticed that, when I load TAQOZ v1.1 from the SD card, the USB power consumption rises and stays at 270mA. In comparison, the version that is hard coded causes the board to consume just 40mA. Also, the DC-DC inductors squeak audibly. That is happening? Is this caused by the higher clock setting?

    Kind regards, Samuel Lourenço
