[bug #43577] Extended address not sent with avr109
Arne Rossius [email protected] Tue 11 Nov 2014 02:14:43 PM UTC
When programming the ATxmega256a3 with avrdude 6.1 (windows version), the extended address is not sent when jumping across a 128 KiB boundary. I have created a text hexfile which only contains data for flash pages 0 (word address 0x00000) and 511 (word address 0x1FF00). However as can be seen from the attached log, after programming the first page only a 16-bit address command ('A') is sent instead of the 24-bit address command ('H'), resulting in an address of 0x0FF00 instead of 0x1FF00. Verify doesn't fail because the same happens when reading, but does fail when programming an actual application (without a gap) larger than 128 KiB.
The programmer is the "xboot" bootloader <https://github.com/alexforencich/xboot/wiki>. The avrdude.conf is unchanged.
Programming the attached hex file does work with the older avrdude 5.11 because this version programs pages 1 to 510 with 0xFF, only sending the address once before the first page and then relying on the bootloader's auto-increment to reach the high addresses. As can be expected, it takes a very long time though.
Also, as can be seen from the xboot source, it resets the extended address byte to zero when receiving an 'A' command. I'm not sure if this behaviour is correct, but if it is, this means that avrdude must send an 'H' command for all flash pages above 128 KiB (unless no address is sent at all between adjacent pages).

The "extended address" is not part of the original AVR109 appnote.
bug #29896 has already been filed to request adding this protocol extension, but has not been handled so far. (Sorry for that.)
Arne Rossius
AFAICS, bug #29896 calls for additional memory types, while this bug is about accessing the area above 128 KiB of the regular flash memory (not bootloader area which is above 256 KiB for xmega256a3), so IMHO it's not a duplicate.
There is already a function in butterfly.c to send the 'H' command (butterfly_set_extaddr()), but it seems that the old butterfly_set_addr() is called instead. Surely this can't be right?

OK, sorry, then I misunderstood it. Reopening it, so I can handle that (hopefully) alltogether.

The test results in #454 show that no issues with ATmega2560 with xboot. But that is based on ATmega2560 with xboot, not ATxmega256a3. Need to get some one to help testing here as I do not have ATxmega256a3. Hopefully Hans can get a hold of the board soon.

https://savannah.nongnu.org/bugs/?29896 is now #200, which is an enhancement request.

The issue here in #360 (or #454) is different. By right, avrdude already supports ATmega256x long ago with the following commit on 30-Jan-2007. https://github.com/avrdudes/avrdude/commit/6fc6e9b184a5fb3cf28ca863f823ed6b84b0638a
This issue here is saying that it somehow does not work with ATxmega2560A3. This needs to be confirmed. So I will change the label.
@MCUdude
Now that you have access to the ATxmega256A3BU Xplained board, please take a look at this one and #404 when you got a chance. Thanks.
I compiled xboot for ATxmega256A3BU, and I'm able to communicate with Avrdude using the bootloader:

It turns out that I forgot to add the -e flag. Now I can get the bootloader to work. I'll try with a bigger file soon.

@mcuee I can confirm that there's an issue writing to addresses above 128kiB.
