Changed Chip & Not work, Please Help me


I was using ESP32-S3-WROOM-1 N8 dev, It’s Good.
and I’m using ESP-PROG, it worked before

but, ESP32-S3WROOM-1 N4 for production changed to chips
Now, It’s Fail!

I changed esp32-s3-devkitc-1.json, for 8->4 flash ram.
but it’s not work.

It’s Booting Log.

Please show your full JSON file and the platformio.ini. Do you set a custom partition table?

Thank for interesting.
