Hi guys
I'm running a Linux embeded system (sysmoBTS) and since two weeks, the device
cannot start up.
here the information about the Loader:
---
sysmobts_v2 Loader v1.1.0 (Aug 15 2012-21:21:49)
Board revision: C.3
Initializing NAND flash:
Bypassing ECC checks

*** Warning - bad CRC, using default environment
A look at the boot process shows that, this process breaks and the kernel is
event not loaded.
I flashed the device and included the log information. Then i realized the boot
process step by step to see where it exactly stops.
here i flashed the device and the following log shows the result.
-
