Hi,

I use esp-at v1.2 project with SparkFun ESP32 Thing, I made some changes in the project and now I can't flash my ESP:
- Changed at_port_write_data() in at_uart_task.c in order to send AT commands with break
- Changed Bootloader log verbosity to no_output
- Changed Uart for console output to none
- Changed Log output to no output

I tried to change Uart for console output back to UART0 and got some errors while trying to flash, like:

Code: Select all

Failed to write to target RAM (result was 01070000)

or

Code: Select all

Timed out waiting for packet header

I tried to change the baudrate and flash with --no-stub, but still got errors.

Does anyone know what caused this problem and how can I fix it?

Thanks a lot!

Hard to say, but note that your changes to the code should not affect your ability to flash the code to the ESP32; something else is going on.
