My Question: How to flash the chip back to the firmware above after an unsuccessful firmware upgrade (Extension for Arduino IDE corrupted something).
Please ignore the red 'fail' error message, I played around with the settings, with 'SpiAutoSet' checked dowloading works.
In operation mode, however, the ESP sends data in an infinite loop which is not to decode. Measured the exact bd rate. Databits=8, SB=1?
Uploading blank.bin to 0x0 does prevent infinite looping.
Thank you for your time.
Flash size 8Mbit: 512KB+512KB, please download :
P.S. boot_v1.2+.bin means the version of boot.bin later than v1.2, we always suggest use the latest version of boot.bin which is boot_v1.4(b1).bin now.
Esp Flash download Tool can read the Flash ID code = 4014h
W25Q40BV ( 4 Mega Bits / 512K Byte ) = ID 4013h
W25Q80BV ( 8 Mega Bits / 1 Mega Byte ) = ID 4014h
W25Q16BV ( 16 Mega Bits / 2 Mega Bytes ) = ID 4015h
W25Q32BV ( 32 Mega Bits / 4 Mega Bytes ) = ID 4016h
W25Q64CV ( 64 Mega bits / 8 Mega Bytes ) = ID 4017h
