Flashing RAK2305 stuck on synchronization process #64

Closed hasanabs closed 1 year ago

hasanabs commented 1 year ago

I have an issue while trying to flash ESP32 WROVER-E (RAK2305 module). When I am flashing my module, it is stuck in the synchronization process. According to the Espressif Flash tools, this issue is because of these problems; Screenshot_20230101_100048 however, I did follow all the instructions.

This is my wiring (using FTDI serial). 20230101_211851

And this is the flashing process that stuck. Screenshot_20230101_102147

Thank you in advanced.

Did you try to lower the baudrate? Try with 115200 baud.

I see two green cables on IO0 and GND, is this the same cable to make sure IO0 is pulled to GND?

I tried with several baud rate, including 115200.

Yes, right, the same cable is pull-down for IO0.

It turns out that my USB TTL was not good; thank you for the help.
