Micronucleus programmer shows 'error: unsupported memory type flash'

[mariusgreuel]

When using the Micronucleus programmer, the error message 'error: unsupported memory type flash' appears:

D:\Temp>avrdude -c micronucleus -p t167 -V -x wait -U flash:w:digistump_digisparkpro_blink_fast.hex:i

avrdude done.  Thank you.

I just took a quick, and it appears that the line is printed here: https://github.com/avrdudes/avrdude/blob/main/src/micronucleus.c#L827

which is called from
https://github.com/avrdudes/avrdude/blob/main/src/avr.c#L988

As the Micronucleus bootloader does not support reading from flash, the option -V must be used. It appears there is now some extra code that reads from flash in avr_write_mem.

with -vvv

avrdude micronucleus_read_byte() [micronucleus.c:827] error: unsupported memory type flash
avrdude: cannot read flash [0x0080, 0x00ff] to pad page

Not sure how to fix this. It appears that the flash is written, however, the padding code is not doing what it is supposed to.

@stefanrueger

Hopefully you have some good idea why this happens. This is a regression so we need to fix it before release.

[mcuee]

I can reproduce this issue using ATtiny85 DigiSpark Clone. So this is confirmed to be a regression. It was confirmed to work with PR #945.

• Fix micronucleus bootloader to check for unresponsive USB devices #945

Firstly I made sure the bootloader works under ATTinyCore (LED is blinking).

Then I burn the bootloader again and use avrdude git main.

Edit: only the error message avrdude error: unsupported memory type flash is relevant, The other errors are due to the use of libusb-win32 driver.

Same problem with ATtiny88 (MH Tiny88). ATtinyCore works fine as it does not avrdude for programming.

| It appears that the flash is written, however, the padding code is not doing what it is supposed to

Well, it does. Read on.

avr_write() for paged memories pads pages with contents that it reads from the memory (ie, uses a read/modify/write cycle). Micronucleus cannot read flash, so it complains. avr_write() does not mind, it just does not pad flash with contents read from the device. However, micronucleus complains that someone tried reading from flash. This error message is a false alarm.

Padding fixes Issue #1050 that AVRDUDE used to treat flash and EEPROM as NOR-memory. Treating all flash as if it was NOR memory is wrong. Only some flash looks like NOR-memory where writing 0xff is a NOP. Whenever the programmer uses a page erase (newer devices) or when it's a bootloader that uses SPM page erase, writing 0xff, well, writes 0xff. This means if you ask these programmers to program 3.5 pages of flash, 4 pages are written and the remaining 0.5 page is overwritten with 0xff. In general, I'd argue that this is wrong. The user might have previously put an important table there. It is worse that this happens to EEPROM.

So, this behaviour (false alarm) is an unfortunate combination of

• Micronucleus being unable to read flash
• AVRDUDE not having a fine-grained model of whether a programmer can read some memories but not others
• Micronucleus complaining in a low-level routine that someone asked to read (rather than letting the caller complain)
• AVRDUDE not having a good model which programmer/memories combos make writing 0xff a NOP

I'd suggest converting line https://github.com/avrdudes/avrdude/blob/main/src/micronucleus.c#L827 from pmsg_error() to pmsg_notice() or pmsg_notice2(). If you agree @mariusgreuel that can be done straight away without a PR.

[mcuee]

@stefanrueger

I think you can proceed with the change. It is good with an ATTiny85 (DigiSpark Clone, original FW which comes with the board).

I still got a warning in the end though, warning: start command failed: Input/output error.

However, the current git main has more issues with the Micronucleus firmware bundled with ATTinyCore. Tested with both ATtiny85 (DigiSpark Clone) and ATtiny167.(DigiSpark Pro clone)

Edit -- the issue is with libusb-win32 driver. Switching to WInUSB (or libusbk) will sort out the issue.

[mcuee]

@stefanrueger and @mariusgreuel

In the end, it is due to the old libusb-win32 driver. If I switch to libusbk or WinUSB driver, there is no issue.

The proposed changes by @stefanrueger is good to go.

to emphasise that it's the reading that is not supported.

[mcuee]

@stefanrueger

Yes I agree with you that the other messgae is probably due to older Micronucleus bootloader firmware and/or due to the use of libusb-win32 driver.

I have since upgraded to the latest FIrmware (either the version from Micronucleus or the version from @mariusgreuel) and switched to use WinUSB driver, the second error message goes away.

And it is important to use WinUSB driver (preferred) and not libusb-win32 driver. That is already mentioned by @mariusgreuel in the wiki.

And your mofification of the message is good to go.

[MCUdude]

And it is important to use WinUSB driver (preferred) and not libusb-win32 driver. That is already mentioned by @mariusgreuel in the wiki.

Maybe Avrdude can warn the user that the USB driver used for Micronucleus isn't preferred?

[stefanrueger]

Downgraded flash read unsupported err msg to notice.

| Maybe Avrdude can warn the user that the USB driver used for Micronucleus isn't preferred?

Good idea. Someone else to do who knows where to warn and what wording.

I will create a new issue to see if we can warn the user for this. I am not so sure if this can be easily done or not.

@mariusgreuel has the avrdude-libusb for Windows MSVC build and there is no problem with either WInUSB driver or libusb-win32 driver in this case.

The issue is probably specific to libusb-1.0+libusb-compat-0.1 with MSYS2.

Take note the official Windows binary will be the MSVC build and not MSYS2 MinGW build.

1. With libusb-win32 driver.

MSYS2 build with libusb-1.0 + libusb-compat-0.1.

You can see these is no way to differentiate the three drivers now.

1. No issues with WinUSB driver or libusbK driver.

Two issues raised against libusb project

• Return kernel driver name -- New API libusb/libusb#1225
• libusb0.sys problem with avrdude programmers like Micronucleus bootloader libusb/libusb#1226
