viewing eeprom contents(viewport, DongleBasic, what can do it?)

mctrivia · 2009-06-30 05:06

No TV, no keyboard, no mouse how can i see the contents of the top half of a 64k eeprom?

DongleBasic was sugested but every time I enter in

dump 32768 32768

i just get syntex error. any other ideas? downloaded viewport but that does not look like it can do it either.

Try the Hydra Asset Manager, I haven't verified it working on non-Hydra boards but as the EEPROM location is standard (pin-wise) I don't see why it shouldn't work.

If you look at the description in the documentation (page 8), you'll see that the syntax is:

dump [noparse][[/noparse] <EEPROM address> ] , <length>

In your case, it would be

dump [noparse][[/noparse] 32768 ],1

This is for the case of the boot EEPROM(s) on I/O pins 28/29.

Not making fun of you ... but that's a riot to me because that was my very first experience with a computer ...

> list
syntax?
>

RTFM?? well the manual gave a list of commands and some example programs, but that was about it ... gag me [noparse]:)[/noparse] Eventually I derived enough from pouring through the manual for it all to make sense (much like using a decoder ring [noparse]:)[/noparse]. After that I had to keep entering my programs by hand over and over again until finally begging a cassette out of my parents. Twas the night before Christmas and all through the house ....

So, you need to dump the contents of EEPROM. Ok, do you know how to make the driver access the EEPROM?
If so, you can dump to the serial port with FullDuplexSerial, etc....

If you like, tomorrow I'll whip up something for you that will work on the propmod I bought. I've been a little tied up [noparse]:)[/noparse]

That would be great I am short of time and trying to make a bootloader for someone with no programmer. I posted my code so far but it does not work

All of the FemtoBasics can also read and write the EEPROM like

EEPROM[noparse][[/noparse] <address> ] = <value>

This writes a byte value to the EEPROM

EEPROM[noparse][[/noparse] <address> ]

This reads a byte value from the EEPROM and returns the value
(which can be used anywhere an expression can be used).

[noparse][[/noparse] <address> ] can also be [noparse][[/noparse] <SCL pin#>,<address> ]
if you want to attach an EEPROM to any even/odd pair of I/O pins

mctrivia · 2009-06-30 06:13

Mike

dump [noparse][[/noparse]$8000],16

did the trick. The first 5 bytes match the image i am trying to copy exactly

00 B4 C4 04 6F

but the image file on the SD has ED next and the EEPROM has FD

You could use DongleBasic's COPY statement. If the SD card file is FOOBAH.BIN, you could do

copy "FOOBAH.BIN",[noparse][[/noparse]$8000]

then compare with what you're copying with your program.

DongleBasic also allows you to sequentially read bytes from an SD file. Look at the OPEN statement
and the FILE "pseudo-variable". It's really quite handy for debugging this sort of thing.

mctrivia · 2009-06-30 06:26

ya it definetly is handy and i am sure i will be using it a lot in the future for debuging. for my purposes i need my code to successfully copy because once done it will be a bootloader that sits on the first half of eeprom and either starts up code on top half(thank you for code that starts top half) or copies the sd card to the top half and start if new code is on there. Doing this way so no mater what code you install on the prop you will never overwrite the bootloader. would be great for people without propplug.

the funny thing is I have used almost the same code to copy info off an sd card.

I am probably just missing something small.

on a hunch i just looked at the eeprom image of my loader. for some reason my code is copying the bottom half of the eeprom to the top instead of the sd card contents. Without donglebasic would have never figured that out.

jazzed · 2009-06-30 06:31

@Mike - Just curious. Why the brackets in the commands?

@mctrivia, The ED and FD you mentioned are the checksum bytes which have about a %0.2 chance of being the same for two different programs.

thanks to dongle basic i have found the pub and my code is sucessfully being copied from the sd card. strange thing is though still not working but that really is not for this thread.

@mctrivia, I think your propmod_us schematic is wrong on propmodule.com ... the uSD connection looks strange.

what looks strange about it? other then I am using 10k instead of 20k and uSD is slightly different then SD it is the same as the schematic in sdspiqasm.

DO pin is connected to RES* ? CLK pin is connected to BOE* ?

yep your right schematic is wrong. each of the connections should be down 2 wires.
