Hi everybody. Hope all well at home and family.

Does anybody know if a winbond W25Q16VSSIG (https://www.digikey.com/product-detail/ ... ND/1929225) works with the ESP32 as a replacement for the 4mb flash?

I did try it and it was able to flash it, at least no error was reported, including the verify hash. But when booting it goes into a reset with the message error code 13 and saying something about spi-flash.

The above chip is a 133mhz and esp32 only allows for 80mhz setup in menuconfig.

Thanks for any help.

Hi.

To be more specific, the console output is

Code: Select all

rst:0xc (SW_CPU_RESET),boot:0x13 (SPI_FAST_FLASH_BOOT)
configsip: 0, SPIWP:0xee
clk_drv:0x00,q_drv:0x00,d_drv:0x00,cs0_drv:0x00,hd_drv:0x00,wp_drv:0x00
mode:DIO, clock div:0
load:0x3fff0018,len:4
load:0x3fff001c,len:1260
load:0x40078000,len:13372
ho 0 tail 12 room 4
load:0x40080400,len:4240
entry 0x40080644

Tried every possible combination of DIO-QIO,40-80MHZ, flashing speed, etc.

It seems as if no firmware was loaded, but the flashing process ended successfully.

Thanks
