Hello,
I use a megadrum stm32F205 lite FW version 20180521 and I search to install a new firmware. I have downloaded mdfwupdate.exe and megadrumSTM32e_56_20230605.bin. I press the left button while I power on the module. On windows 11, I run the command : C:\Users\tapil\Desktop\mdfwupdate.exe megadrumSTM32e_56_20220530.bin

I choose the midi in port, the midi out port then press enter and :
Retrying on crc error
Transferring..-0% done.
Retrying on crc error
Transferring..-0% done.

I have disactived windows protection, change the firmware with megadrumSTM32e_56_20230605.bin
Still the same.

If someone could help me

Thanks you in advance

I suspect that while you were trying to do it in Windows 11 there was another app running which was unintentionally opening the same (all available) MIDI ports causing a conflict.
