Megadesk continuous rebooting when trying to flash

[TASSDevon]

Hi

I'm trying to flash the serial enabled firmware onto the board (so I can hook up an ESP)
I'm currently using USBasp (https://www.fischl.de/usbasp/) programmer, set to 5V.

Connected all 6 pins, when I connect it to the USB port, I hear the 3 startup beeps continuously.
When I do the first command:

% avrdude -C/Users/devon/Library/Arduino15/packages/ATTinyCore/hardware/avr/1.5.2/avrdude.conf -c usbasp -p t841 -U lfuse:w:0xe2:m

avrdude: set SCK frequency to 187500 Hz
avrdude: AVR device initialized and ready to accept instructions

Reading | ################################################## | 100% 0.00s

avrdude: Device signature = 0x1e9315 (probably t841)
avrdude: reading input file "0xe2"
avrdude: writing lfuse (1 bytes):

Writing | ################################################## | 100% 0.00s

avrdude: 1 bytes of lfuse written
avrdude: verifying lfuse memory against 0xe2:

Reading | ################################################## | 100% 0.00s

avrdude: 1 bytes of lfuse verified

avrdude done.  Thank you.

This works but any subsequent command fails, even if I redo this one, only way to be able to successfully do it again is to powercycle. Any ideas what's going on here? I tried feeding it 5V from the programmer instead of from the desk but that made no difference (obviously not at the same time).

You could try lowering the flashing speed to see if that helps? I've never had much luck with the USBAsp.

Yep, that did the trick, used -B 32 and it worked flawlessly!
