Forum Post: RE: Reading SPI Flash ID in U-boot

Vimal,

[quote user="Vimal Gupta"]  mode = 0;[/quote]

Can you try with mode = 3

[quote user="Vimal Gupta"]  slave = spi_setup_slave(bus, cs,1000000, mode);[/quote]

Can you try with max speed of 75000000:

spi_setup_slave(bus,cs,75000000,3);

[quote user="Vimal Gupta"]spi_claim_bus(slave);[/quote]

You should add error check:

 rcode = spi_claim_bus(slave);
    if (rcode) {
        printf("SF: Failed to claim SPI bus: %d\n", rcode);
        goto err_claim_bus;
    }

err_claim_bus:
    spi_free_slave(slave);
    return NULL;

Let me know the result.

Regards,
Pavel
