I'm trying to flash a Wemos D1 mini ESP8266 board with the blink sketch, but get an error. The built in LED turns off when flashing starts.
Sketch uses 247872 bytes (23%) of program storage space. Maximum is 1044464 bytes. Global variables use 28000 bytes (34%) of dynamic memory, leaving 53920 bytes for local variables. Maximum is 81920 bytes. warning: serialport_set_baudrate: baud rate 921600 may not work warning: espcomm_sync failed error: espcomm_open failed error: espcomm_upload_mem failed error: espcomm_upload_mem failed
I tried changing the programming speed to most of the other options.
If I open the serial monitor and set the baud rate to
74880, I get the following message repeatedly.
Fatal exception (0): epc1=0x400cd530, epc2=0x00000000, epc3=0x00000000, excvaddr=0x00000000, depc=0x00000000
Is the board dead, or is there a way of reflashing it without using the serial port?
