ESP8266 overlap mode The library supports SPI overlap on the ESP8266 so the TFT screen can share MOSI, MISO and SCLK pins with the program FLASH, this frees up GPIO pins for other uses. Only one SPI device can be connected to the FLASH pins and the chips select for the TFT must be ...

Be careful when building the bootloader that the resulting image (.bin) does not exceed 24k, or it will overlap with the partition table. The compiler / linker does not warn about this (at least in IDF 3.0.x). Try setting a lower log level for the bootloader. ...

ESP-IDF v4.4 ESP32 I want to use BLK3 eFuses in a custom efuse table, but they overlap with MAC_CUSTOM* and ADC* fields from the common esp_efuse_table.csv. The same issue was dealt with here, but for ESP32-S3, which has a different esp_...

I also tried by setting the offset to 0x0000, the overlap error gone but after flash, esp not able to read the bootloader. error showing like "failed to read". Contributor ravibhagavandas commented Mar 22, 2021 Hi @Raghav3107 , I think from the error log it looks like the first part...
