Hello Sir, Please find attached my driver file. The function spi_flash_alloc_base declaration was added to include/spi_flash.h and definition to drivers/mtd/spi/spi_flash.c.

Yes - It's looks fine but.

Hello All, I am using a custom ARM based development board running u-boot from PNOR memory. However, it does not have support for the Micron SPI flash memory (N25Q064A). I have added support for the micron memory in drivers/mtd/spi/stmicro.c file and included the flag CONFIG_SPI_FLASH_STMICRO in the config file and recompiled the u-boot source source. Then, ran it directly through RAM memory. The new u-boot ran from RAM. Now when I run sf probe 0 command I get the following output Got Idcodes 000000: 00 00 00 00 and the code hangs after this.

This log should not be all 0's #ifdef DEBUG printf("SF: Got idcodes\n"); print_buffer(0, idcode, 1, sizeof(idcode), 0); #endif

The idcode details comes from drivers/spi while reading flash ID code. Check with your driver once and it's good to try to latest u-boot.

Looks like your driver itself is not returning any proper idcode.

What id details you added - I think you're using old u-boot no stmicro.c in current u-boot, please re-base to master and try.

thanks!
