closedby AZhi-hubopened 2025-07-11updated 2025-07-13
bug

Port, board and/or hardware

Reproduction

In according to official guidance , open powershell echo:
esptool --baud 460800 write_flash 0 .\ESP32_GENERIC_S3-SPIRAM_OCT-20250415-v1.25.0.bin
click RST button,and open thonny,execute

import esp
import gc
print(esp.flash_size())
print(esp.flash_user_start())
print(gc.mem_free())

you will find a problem like result below.

  • First line is flash size ,equals 8M,corresponds to rom
  • Second Line is user partition start,I know,ESP32_GENERIC_S3-SPIRAM_OCT-20250415-v1.25.0.bin is 1.5M , from 2M maybe reasonable.
  • Third Line is mem_free, corresponds to ram .

8320080

Actually my board is N16R8, means 16M psrom and 8M psram. after using Micropython bin, I got 8M rom , and 8M ram ,where is 8M left from flash?
I chose OCT version bin due to 8M psram, but normal and OCT version both miss flash size. I don't know why and how i need to do or it's something being limited.
And thonny is also 6m,maybe 8M-2M?
