Sporadic crash during flashing #1061

I'm programming an ATtiny 1614 directly from the serial port on a Rasbperry Pi (with appropriate diode and resistors) using the Arduino IDE 1.8.19. The ATtiny is on a Raspberry Pi hat, so connections are via circuit board traces, not cables. As the program I am working on has gotten bigger and more complete, I have started getting crashes during flashing. It is not consistent - if it fails and I immediately repeat it, it might work. It didn't happen when the program was smaller, so my guess is that as the program got bigger some situation that was marginal to begin with turned unfavorable. Does this dump offer any clues?


Sketch uses 3609 bytes (22%) of program storage space. Maximum is 16384 bytes.
Global variables use 105 bytes (5%) of dynamic memory, leaving 1943 bytes for local variables. Maximum is 2048 bytes.

This report would have more information with

And here is another failure message that I sometimes get from a slightly different version of the program. Sometimes uploading ends with the "expecting ACK after ST" error above, sometimes with the "bytearray index out of bounds" message below and occasionally it doesn't fail.

It turned out to be a serial performance problem. Adding write delays or moving to a slower speed than 230400 fixed it.
