bin 2.5.0 not working. Blank screen, no output

[Believeinus]

bin 2.5.0 showing black screen on esp32 30 pin. 2.2.1 works but 2.5.0 is black screen, no output

[Nicoldik]

hi, I have this problem too, I suspect it's either esp32 or oled screen.

[Nicoldik]

hello, I understand what the problem is. the problem is that esp32 is limited in 4MB versions (let's not mention versions with 8mb and 16mb of memory) of files up to 1.31 and the firmware weighs 1.54MB. you need (the firmware author) to make bootloader.bin and partitions.bin for the firmware

Same issue, 2.2.1 flashed ok and displays on the oled, but 2.5.0 does not display. serial monitor output

Tired a ESP32-wroom-32D, ESP32-wroom-32U no luck on 2.5

kosmostrater the line "E (505) esp_image: Image length 1553536 doesn't fit in partition length 1310720 E (505) boot: OTA app partition slot 0 is not bootable E (505) esp_image: image at 0x150000 has invalid magic byte (nothing flashed here?)

I believe it says somewhere to use the 16mb version. I just don't remember where I seen it
