It certainly looks like it is not able to identify the chip after the bootloader hands off control to the main app. Does this work with a basic esp-idf app or a custom driver?

[faizannazir]

I am able to flash again it was not entering auto download mode using rts and dtr so i enter manually but still it printing spi flash memory 0k and keep rebooting

[lbernstone]

What do you get if you run esptool chip_id?

[faizannazir]

[lbernstone]

Sure does sound like unsupported hardware. 4MBit is not enough to boot arduino-esp32. As suggested, compile a firmware in esp-idf, and then submit the issue upstream.

[faizannazir]

How you guess flash size?

[faizannazir]

I had tried idf it also give same error instead 4MB It gives 2MB error

[faizannazir]

Currently it has this chip AT25SF041B-SSHB-B
I am thinking to replace it with W25Q80RVS This flash chip support esp32?https://www.mouser.co.uk/ProductDetail/Winbond/W25Q80RVSNJQ?qs=mELouGlnn3eiLlSxpfAziw%3D%3D

Look through IDF source code which flash chips are supported.

[lbernstone]

W25Q80RVS will likely be recognized, but 2MB (16Mbit) is the smallest supported by the framework.

How you know its unsupported and size of flash 4Mbit?

[lbernstone]

I know it is unsupported since it is not recognized by your device, and there is no driver for Renesas chips. I know it is 4Mbit b/c I read the datasheet.
