Hi. I have an important problem with a TS-7553 board. I have found
this problem with SPI flash linux, NAND and SD Card images (
ts-arm-sbc/ts-7500-linux/binaries/ts-images/2gbsd-eclipse-may252010.dd.bz2 and
2gbsd-eclipse-jun012010.dd.bz2).
What i have observed is that, when under write operations on a USB
external memory attached to the TS-7553, the board reboots unexpectedly. Look
at attached example: while i can create without problems a 100MB image on the
external USB, a read/write operation like a cp reboots the board in seconds.
Observe also that i'm using SPI flash linux. The same behavior is
observed in SD Card full debian linux. And it is not a problem of the external
USB memory: i have reproduced this behaviour with serveral memories. Moreover,
the board reboots when doing read/write operations on the two USB ports, but
also on the Host USB port (seen when using g_file_storage module).
This problem is reproduced with FAT and ext2 filesystems on the USB
memory.
Do you have any idea why this happens or how can i debug this for
gathering more information??
Thanks in advance.
