Hi Javier,
Even when passing the chip-select to sf probe says to be optional, it makes "sf erase" and "sf write" to fail on a mx6qsabrelite board. e.g:
MX6QSABRELITE U-Boot > sf probe 1 MX6QSABRELITE U-Boot > sf erase 0 0x40000 SPI flash erase failed MX6QSABRELITE U-Boot > sf write 0x10800000 0 0x40000 SPI flash write failed
Well, the real reason is that the passed chipselect is wrong. Checking in the configuration file, I see that the value to be passed should be 0x7300. I suppose (I am not testing) that "sf probe 0x7300" make sf erase and sw write working.
It's 0x5300 as listed in commit c1173bd0.
And the SABRE Lite README definitely needs updates.

Eric
