Firmware upgrade for a very old Firmware updated unit

[lawrence_doss]

Does anyone know what is the Firward to update in a very old Megadrum module that I built.. it has the 20130405 Ver on it.. I tried uploading the new firmware and it is failing.. (been out of this for a long time)...

You should be able to update to the latest version from 20130405. I'm guessing you're doing something wrong while trying to update the firmware.

Thanks DMITRI. Will try again. Can you please let me know which of the firmwares I need to upload (megadrum644_48_20230605 / megadrum1284_56_20230605 / megadrumSTM32a_56_20230605 / megadrumSTM32b_56_20230605 / megadrumSTM32c_56_20230605 /megadrumSTM32d_56_20230605 / megadrumSTM32e_56_20230605 / megadrumSTM32f_56_20230605 / megadrumSTM32g_56_20230605.

Have completely forgotten which processor that I had used to build it..

If you built it yourself then it is Atmega644 based.

As per viewtopic.php?f=3&t=1252 the step 3 will show you the CPU version of your MegaDrum.
