SerialUPDI - unable to write USERROW memory on AVR64DU32 #1655

Closed dbuchwald closed 6 months ago

dbuchwald commented 6 months ago

First reported by @MCUdude in discussion #1473.

This issue is related to SerialUPDI programmer and first ever tested DU chip, and it's pretty easy to replicate:

Root cause of the issue is the fact that so far all the USERROW memories were 64 bytes or smaller, and the implementations so far were based on the sequence of "set pointer; repeat ; write byte and increase pointer", which was fine as long as these memories were 256 bytes or less (this is limitation of the repeat command which takes single byte as a parameter.

Most probably the fix would be to change the USERROW write operation to "set pointer; repeat <number_of_bytes/2>; write 2-byte word and increase pointer", but this could introduce regression to all the old parts, so this needs to be tested carefully.

It would also be very helpful to have access to the datasheet of the chip in question, it might actually contain some guidelines for handling such a large memory.

@stefanrueger, @mcuee, @askn37 - do you think I should add any additional information here?

dbuchwald commented 6 months ago

@MCUdude I have prepared preliminary fix, which should not introduce any regression for previously tested chips:

https://github.com/dbuchwald/avrdude/tree/issue_1655

Can you check if it fixes issue on AVR64DU28?

Basically the change is that if the USERROW memory is larger than 256 bytes then word-based write operation is performed instead of the previously used byte-based write.

I have also tested word-based write of USERROW against AVR16EA28 and it seems to have worked just fine, so maybe some day we could simplify code by changing to word-based write for all the UPDI AVRs, but I wouldn't introduce this so late into release cycle.

askn37 commented 6 months ago

do you think I should add any additional information here?

I agree that you are absolutely right.

The maximum amount of memory that can be written with one set of repeated commands is 256 words, which is consistent with all known datasheet descriptions. At least I haven't read anything else written. And this is probably the upper limit that can be achieved with his current UPDI system. If a page size of 1024 bytes appears in the future, I think the specifications will probably be expanded or some kind of improvement will be proposed at that time.

I'm away for the weekend, but will be back and can continue testing on Sunday evening.

But is the userrow size 64 or 512 bytes?

dbuchwald commented 6 months ago

Sure, sorry, didn't mean to rush you.

But is the userrow size 64 or 512 bytes?

For a minute I was hoping it was 64 bytes but no, after inspecting atpack and pymcuprog source I came to the conclusion that the size of USERROW memory for AVR64DU32 and AVR64DU28 is, indeed, 512 bytes.

askn37 commented 6 months ago

It is stated on page 3 to 4 of the brief note.

Even in this document, it is unlikely that you are confusing it with bit amount.

The following products have been registered on Mouser and DigiKey.

FBP-AVR-DU-ISO26262 Development Software ISO 26262 Functional Safety Basic Package for the AVR DU MCU Family Factory Special Order: Obtain a quote to verify the current price, lead-time and ordering requirements of the manufacturer. https://www.mouser.fi/ProductDetail/Microchip-Technology/FBP-AVR-DU-ISO26262?qs=mELouGlnn3ezslVP1LToMA%3D%3D

It appears to be a development kit to obtain ISO 26262 approval. I had no idea it would be possible to pre-order items like this before the individual chips went on sale.

From this, we can infer that an automotive-grade derivative of AVR-DU also exists. This suggests that there may be signatures that differ from the usual products, such as the ATtiny416auto example.
