Dear sir,
We are interfacing MPC8xx processor with IDE/HDD by using Memory
controller.In U-boot we configured CONFIG_IDE_8xx_DIRECT(PIO 4).
The Logic implemented is interfaced with the User Programmable Machine B
(UPMB) of MPC’s memory Controller unit.
MPC860/866 at 80MHz/100/130Mhz.
We are able to detect the HDD at the U-boot prompt(IDE status = OK and
status register value is 0x50).
But when we run it from kernel with rfs mounted on HDD it shows the
following error.
I've captured the log of IDE with debug enabled.
Please do have a look at it & Kindly let me know where we went wrong.
