Hi,
We use custom hw which is very similar with hawkboard (AM1808, Silicon Revision 2.0, MICRON MT29F1G08ABCHC NAND, vs ).
Some devices that worked well approximately 3 months don't boot(Nothing prints to console).
If we operate the hw in the UART boot mode and flash the boot image( created with AISgen utilities v1.13) again,
it boots up correctly on NAND mode.
We don't know when the problem occurs again.
Document "Using the OMAP-L132/L138 Bootloader" indicates fixes of many NAND boot hang problems (http://www.ti.com/lit/an/sprab41e/sprab41e.pdf, page 40)
between silicon revision 2.0 and 2.1. Our products use version 2.0
Is this a ROM boot loader problem? How do we fix the problem?
