Thanks for the suggestion, but no joy. I changed to a different port number and no joy there, either. There's transfer activity indicated on the board and the failure message pops up after the 100% mark.
Are you sure you're commenting on one problem with both device not found and transferring to end of file?
I know I'm likely stating the obvious, but are you switching to PGM before turning the board on?
Yep, the switch was set to PGM. All previous updates have gone without a hitch. I'm currently on v9b and I went through the update procedure using the v9b px and image and got the same behavior and error message, so this is something new.

Are you sure you're commenting on one problem with both device not found and transferring to end of file?
Yes, the load looks like it's progressing, both on the board and the PX progress bar. The COM port error pops after the load progress hits 100%.
I had a similar problem... try quitting out of PNUT while you are using PX. In my case it wasn't PNUT, but another utility... that while not using COM4 but was running at the time and may not have released COM4 correctly.

In the short term, I have a BE-Micro A2, but it's been quite a while since I used it, and I've never loaded a P2 image on it. Is it as simple as using PX to load the zip's *A2*.jic file?
No you need to use the Altera software to load that in, unfortunately. There is a stand alone programmer from Altera - you don't need the whole giant package
Thanks, that jogged my memory. I'll grab the stand-alone programmer.
I tried updating to P2v10a (Prop 1-2-3 A9 board) and PX complained with a "PX loader not found on COM3" message.
Doh!
Looks like it was a not-very-old USB cable. P2v10a looks to be loaded and working. Since it looked like bits were flowing, the stinkin' cable was not very high on my trouble-shooting list
Thanks for that instruction summary Ray, I was wondering about the current state!
Serial bootloader
BTW, does anyone have a clue about what I need to do for the serial bootloader? I'm sure the info is somewhere but whether the stuff I find is the most current or not is the issue. I want to put together a small PIC + EEPROM to load up an SPI Flash and SD bootloader for testing. Once I can get the SD bootloader to work then that should give everyone something to chew on. I know I could probably just load this bootloader up serially and I might do that initially but the PIC idea is to make my system stand-alone as I want to deploy it in an actual project for some real field tests! I have a few other CV-A9s around here fortunately so I won't be stuck for test units.
I think I'm going to keep using the ".spin" extension (if I can) so I can keep using the Prop Tool for code editing. Looks like the new PNut is ".spin2" only, but I think I can just change filter to "*.*" and use .spin files...

I think Chip has to be close to getting SPI boot ROM in beta form ?

Or, you could use a Silabs part, as I think you can program those via a Prop ?
Check with Chip on the Boot timelines, as if you can tolerate serial for a while, a prelim BOOT is likely not far off.
You sound like a good test case for BOOT testing
Or, you could code a SPI boot and get Chip to do a build with that in ROM ?
I think I'm going to keep using the ".spin" extension (if I can) so I can keep using the Prop Tool for code editing. Looks like the new PNut is ".spin2" only, but I think I can just change filter to "*.*" and use .spin files...
Or use the VSCode extension, which will give you syntax coloring (for now).
VSCode looks pretty good. I'm just used to Prop Tool, been using it for years.
If I weren't so entrenched, I'd definitely use your extension and VSCode.
I'm editing my Spin files in Context under WINXP in VirtualBox at present due to this Wine bug glitching the reset line but I have execute keys (using F11) in Context that allow me to callup PNut with the file name but does PNut have any command line parameters available to get it to F11 then exit?

I can add that.
That would be so George Jetson, all I would have to do is press one button all the time. Yay!
Taking some time off to wire up one of the CV-A9 boards to a Vector Electronics double-side matrix board using pin headers to mount it upside down. Then I can attach all the other parts I want to test including the Serial Flash and IoT5500 and RS485 and many other parts, perhaps even a module for the VGA DACs. Main thing is I want to double-check the basic Serial Flash bootload process then use that to check the SD bootloader.
@Chip: did you get the command line F11 done for PNut? My George Jetson finger is getting mangled and could do with a rest
I looked into back-ordering the BeMIcroCVA9 since it does no good to just keep checking in the hope that somebody does order it. I've been given a lead time of 17-18 weeks which brings us to the end of October. This is a very nice board and I will be doing a controller motherboard for this including a footprint for whenever the P2 chip becomes available. So please indicate your interest as I can order more now and even though it's a bit of a wait it will come around soon enough and certainly a lot sooner than P2 itself. Besides, the motherboard I am doing for it will be worth it too! This thing is already rockin'!

Chip,
Here are a couple of instruction opcode swaps that may make the decoding more efficient, and the compilers simpler, and instruction set look more regular.
These just make the first set of instruction opcodes 0xxxxxx identically formatted.
You might not want to change anything. If you are interested, there are a few changes in the 1xxxxxx that may make sense too.
BTW I posted the whole instruction set summary a few posts back.
I have been looking at the smart pins for async.
WRPIN sets the mode, WXPIN sets the baud/length.
WYPIN writes the data byte/word/long, RDPIN reads the data byte/word/long.
This seems wrong to me. I would think WRPIN & RDPIN should write/read the data, while WXPIN & WYPIN should set the mode & baud/length.
Have I got this the correct way around???

Yeah, it's a side effect of the old register labelling. Chip appears to have kept the X and Y references while ditching the M and Z references. A small name shuffle presumably will fix it.
I have struck a problem getting smart serial to work.
Send works fine, but receive doesn't seem to be receiving anything. I am using PST connected to the propplug.
Can anyone see my bug?
BTW I have discovered that if you don't transmit a character, then the instruction
