I flashed Jetpack 2.3.1 onto TX1.
Downloaded kernel source code of Release 24.2.1, built and copied the root file system to SD Card.
TX1 is successfully booting from Flash memory. But failing to boot from SD Card.
Note: extlinux.conf is copied properly.
Initially TX1 booted from SD Card. Later I restarted the board by inserting SD Card and it stopped booting from SD Card. Same SD Card is working on other board like J100.
Unable to resolve the problem. Any help is welcome.
