Z150 AT, Compiled Hex will not work

[Alectardy98]

I have tried to compile a hex from the source code for the zenith Z150 AT and it does not work, and when the keyboard is plugged in, it repeats this code.

This only happens when I try to compile, the online configuration tool works with no problems

Here is the referenced code

What's your gcc version?
What if checkout 27e6c8d(which is used with online editor) and buid firmware?

I use avr-gcc 5.4.0 on ubuntu 20.04 to build firmware for reference.

I am currently using AVR GCC 9.3.0, on mac OS 12.4 and I'm using the most up to date build of TMK

I checked out 27e6c8d and still was giving me the issue, it must have to do with the AVR GCC Version

[Alectardy98]

i also have just tested on manjaro Linux and I am getting the same issue

[tmk]

which is gcc version of manjaro Linux?
You see any warning or error during build process?

I'll try new version of GCC when I have a chance.

[Alectardy98]

no, I didn't see any errors, but it was the most up-to-date version. It was 12 something.

[Alectardy98]

I have a friend who has ubuntu, and the most up to date version of TMK. He has avr-gcc 5.4.0 and the hex he made is working. I think its an issue with avr-gcc

[tmk]

I will have to check GCC release notes about AVR closely. Something changed between 5.4 and 9.3 and it exposes bug or incompatible of my code probably.

I confirmed the problem on Archlinux with avr-gcc 12.1.0.

At this time workaround seems to be removing -ffunction-sections option.
I'm not sure how this option causes inside.

I appear to be having the same issue, or at least a similar one, over here on GCC v9.4.0.

Worth noting that the files generated if I run a make are much, much smaller than the ones precompiled. I've tried rolling back to old commits etc. and compiling from those, but no dice. I just tried commenting out CFLAGS += -ffunction-sections in rules.mk under tmk_core and that didn't work for me, although it did make the compiled file much larger.

Update: rolled back manually to avr-gcc v5.5.0 and now getting a different issue: compilation fails, with this error:

section .keymap LMA [00006800,000069ff] overlaps section .data LMA [00006772,0000680b]
collect2: error: ld returned 1 exit status
make: *** [ibmpc_usb_atmega32u4.elf] Error 1

Further update: ran the VM from the wiki which is on avr-gcc v5.4.0... and it still wouldn't compile... until I disabled mousekeys, which are enabled by default in the makefile. Then it finally worked.

I suspect this might be something to do with why there's a problem. When I disable mousekeys then try to build on avr-gcc v9.4...

lto-wrapper: warning: Options to Xassembler do not match: -adhlns=obj_ibmpc_usb_atmega32u4/unimap_plain.lst, -adhlns=obj_ibmpc_usb_atmega32u4/protocol/ibmpc.cpp.lst, dropping all -Xassembler and -Wa options.

Apparently forcing LTO off should prevent that issue, but I tried adding that, and it compiled, but still didn't actually work.

So, my next move was switching back over to avr-gcc v5.5 (the oldest I can access via Homebrew), unlinking my still-installed v9.4, and trying a compile with mousekeys disabled. That worked:

TL;DR: To compile the IBM PC converter, the Mouse Keys feature appears to have to be disabled, and avr-gcc has to be rolled back significantly (I tested at v5.4 and v5.5, I'm about to check v8). Obviously, this is not a great position to be in longer term but it at least works short term.

Currently GCC 7.3.0 supported officially by Microchip is recommended. Confirmed that 5.4.0 also works.

https://github.com/tmk/tmk_keyboard/wiki#avr-gcc

GCC 5 and 7

Confirmed that GCC 5.4.0 and 7.3.0 works adding this change in Makefile. -Wl,--relax resolves firmware size issue with those GCC version.

GCC 8-12

LTO(link time optimization) doesn't work with my C code. This makes firmware size bigger.

GCC 8-9

LTO(link time optimization) doesn't work also with my C++ code. This makes firmware size bigger.

Makefile

With GCC 8-12 you cannot build with default configuration due to size issue. You have to disable some feature, COMMAND_ENABLE is disabled here for example.
