I want to flash esp-link but I can’t get it to flash, just
A fatal error occurred: Failed to connect to Espressif device: Timed out waiting for packet header
Do I have to do something with the EN pin? I would prefer to not have to de-solder/swap the ESP12F like @Atlantis
EDIT: Never mind, You have to ground R6 (inner side towards connector, not towards edge of board) and reset (R5), then you can let go of both, bit finicky but its fairly safe, with esptool.py --connect-attempts 0 helps a lot.
Highly recommend anyone trying this back up the stock image first esptool.py --connect-attempts 0 -p /dev/ttyUSB0 -b230400 read_flash 0x0 0x400000 original_fw_4m.bin
And this is what I used to flash it esptool.py --connect-attempts 0 --port /dev/ttyUSB0 --baud 115200 write_flash -fs 32m -ff 80m 0x00000 boot_v1.7.bin 0x1000 user1.bin 0x3FC000 esp_init_data_default.bin 0x3FE000 blank.bin
EDIT2: What should I set for pins in the UI
