Hi All,
We are using DRA6 processor with TI-sdk 7 . We are having issues in flashing NAND from u-boot. When we try to write large size of data it gives subsequent time outs before it writes the data successfully. We are using 512Mb NAND . We tried booting from SD card and tried nandtest utility to test nand. I am attaching the logs of nandtest in a file
This Timeout issue is random. After 4-5 timeouts we are able to write image on the NAND. Kindly see the logs :
