Hello All,
We have am335x based board. We trying to boot the kernel and mount the root file system. The u-boot loads the kernel perfectly with access the MMC initially, but when kernel starts to access the MMC block p2 to mount the file system . We got the errors of the I/O related to MMC. The file system doesnot read properly, due to this its not mounted propery, but sometime we got the root prompt.
We formated the card twice, and also changed the card . but we faced some problems. can you please tell us what might be the problem. How we make the diagnostic for same.
The error logs as follows.
