How to write flash status
Posted: Fri Jan 08, 2021 5:01 pm
Hello all,
My equipment met a problem. After working for some days(especially when the battery resumed from running out), it would show this error.
Chip version: ESP32D0WDQ5 (revision 1)
ESP-IDF: V3.0.9
After I used esptool.py to rewrite the status of flash to 0x0000, this error can be fixed. However, I want to know how to reset flash status by C, then our clients don't need to ship the equipments back.
I have found esp_rom_spiflash_write_status in spi_flash_rom_patch.c, but it didn't work after I call it.
Thanks for your help in advance.
