TFTP Bootloader stops after first upload?

Post by plains203 » Mon May 14, 2018 10:02 am

I have the TFTP bootloader working for on boards and can upload a sketch once via tftp. Once that has been uploaded it works but I cannot get the board to accept another upload via tftp. Upon reset the board never flashes the led to indicate it is waiting for an upload anymore. Any ideas anyone?

I ended up using a different bootloader and got this working. The bootloader I started using has issues with reading ip settings from the eeprom. I didn't debug that and instead just changed the address settings in the bootloader code and flashed that. This was in some ways better for my application. It works quite nicely now.
