Hi,
I boot up the OMAPL137 EVM with the User Interface Module attached(both are from SPI) and try to work with the nand flash on the UIM. When I mount the nand flash, it shows the following errors or warnings:
root@192.168.71.4:/mnt# mount -t jffs2 /dev/mtdblock3 /mnt/nand4G
CLEANMARKER node found at 0x00000000 has totlen 0xc != normal 0x0
Empty flash at 0x0000012c ends at 0x00000800
Erase at 0x06680000 failed immediately: errno -5
Despite these errors, I can find the content that was wrote to the nand flash. And I know "Empty flash at 0x0000012c ends at 0x00000800" is due to the nand flash is partially written. But it still confuses me how come the "Erase at 0x06680000 failed immediately: errno -5". Even google can't find much about it.
And another problem which maybe I should open another thread to ask: The board boot up with NFS. The network file system is on a linux host(VMPlayer ubuntu). I can access the nand flash on the board using Tera Terminal, but on the linux host, cannot find the the content at the supposed mount point in NFS. The NFS seems working well. Files created/deleted in directory: /opt on either end can be find on the other.
Please help me,
thanks!
