although this is a bit harsh, i'm inclined to agree. last time i tried this driver, apart from reading from a spi flash, nothing else was working. even a spi unlock was broken. if you actually capture the spi pins on a scope you see that mostly garbage is transmitted in some cases (eg. using the raw spi commands on the cli). fun fact: the spi unlock actually resulted in a spi lock ;) i guess freescale haven't put much love into this one ;) -michael _______________________________________________ U-Boot mailing list U-Boot@lists.denx.de http://lists.denx.de/mailman/listinfo/u-boot
