So I can now write and read data on the GD25B512MEYIGR chip with the idf.py flash commands, and esptool read_flash and write_flash. esptool.py --port /dev/ttyACM0 read_flash --flash_size 64MB 0x0 0x10000 test esptool.py v4.8.dev4 Serial port /dev/ttyACM0 Connecting.... Detecting chip type... ESP32-S...

Hello again :) So I changed the chip with a GD25B512MEYIGR that is detected by the esp32s3: esptool.py --port /dev/ttyACM0 flash_id esptool.py v4.8.dev4 Serial port /dev/ttyACM0 Connecting... Detecting chip type... ESP32-S3 Chip is ESP32-S3 (QFN56) (revision v0.2) Features: WiFi, BLE Crystal is 40MH...

Thanks for the information.

Is GD25B512MEYIGR fully supported ?

Is there a source code I can refer about fully supported chips ?

Hello, I made a PCB with ESP32-S3 and a 512Mb external SPI flash (F35SQA512M-WWT - 512Mb - up to 133Mhz) I already did several other esp design with external flash but it seems I missed something on this one: - I have GPIO 45 pulled down so the VDDSPI = 3.3V - the SPI flash is connected to the ESP32...
