Hi,
I'm working on a SPI driver and i have a small but difficult to solve problem on
my MPC852T : a "conflict" between SMC1 and the SPI bus. In fact the data i send
on the spi bus are always preceded by a corrupt byte unless i do a printk() call
while i m sending.
I have made some hypothesis about this bug but i can't really figure out what
really happen ( is it due to the shift register which is badly initialised or
the SDMA channel that did not do its job ... ? )
Any help would be greatly appreciated .
Pierre Sutra
