Hi, still no-one to answer this question ?

Hello I would like to know it there is a compatible 512Mb flash for esp32 s3 and or p4.
By compatible I mean for it to be the only flash with data and instructions.

Right now I only found 256Mb flash that can run app.
I managed to use a 512Mb flash, for example GD25B512MEYIGR, but only for data ...

Hello, check https://github.com/espressif/esp-h264-component/ and https://github.com/espressif/esp-h264-c ... t/issues/5

Decodes H264, no mp4 and aac support in the module but you can check in ESP-ADF for mp3 decoding.

Hello I think someone may have encountered the same problem as described on esp32 h264 module here :
https://github.com/espressif/esp-h264-component/issues/5


I'm trying to decode H264 video with ESP32-P4.

I encode a video this way :

ffmpeg -y -i gundam.original.mp4 -c:v libx264 -profile:v ...

Can't wait ! The p4 is really an exciting mcu !

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 ...

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 ...

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 ...
