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.
Regards,
Eric
