Firmware too large for Type 4 / CUL_V3 868MHZ

[derjohn]

Since several releases there is a too large firmware shipped. ( Iooked into the last 5 releases)

E.G: I see:
-rw-r--r--  1 aj aj  73K Mär 30  2017 CUL_V3_433MHZ.hex
-rw-r--r--  1 aj aj  80K Mär 30  2017 CUL_V3_868MHZ.hex

I can flash the CUL_V3_433MHZ.hex without issues, but the CUL_V3_868MHZ.hex gives me:

Flash now device
Call: dfu-programmer atmega32u4 erase
Call: dfu-programmer atmega32u4 flash CUL_V3_868MHZ.hex
Bootloader and code overlap.
Use --suppress-bootloader-mem to ignore
Call: dfu-programmer atmega32u4 start

Can you reduce the code size (features?) for the particular FW? I look like 73K fits into the CUL, but 80K is too much. Could you add an test in the build step that fails, it the foo get too big?

This one is small enough:

Same problem here. Current version is 81.4 KB. Your second post seems to be a solution but to be honest I do not understand a single word. Can you pls explain what to do?

@petjek There is a file culfw/Devices/CUL/board.h b/culfw/Devices/CUL/board.h, remove the lines marked with "-" and compile the new rom. Yes, you need to compile. If you can't, I can provide you a binary.

[petjek]

@derjohn Never really compiled before so if you can provide the binary I'd use that instead.

EDIT: now that I installed make and all the other dependencies I think I can compile the binary. Running the flash.sh script will do that job I guess?
