Unable to flash Lily Go #9

Closed jampez77 closed 1 year ago

jampez77 commented 3 years ago

Hoping someone can point me in the right direction. I have the Lily Go and can observe in a serial monitor that it is working as I can enter download mode this method:

https://github.com/Xinyuan-LilyGO/LilyGo-T-Call-SIM800/issues/89#issuecomment-686185252

However I get the following error A fatal error occurred: Failed to write to target RAM (result was 01070000).

Here is the full terminal log.

Looks like the memory address config is not correct, have a look in the ESP bootloader memory layout config and try out a few options. Try erasing the flash first as well.
