Hi,
I'm using micro 2440 board with supervivi and kernel 2.6.32.2.
I was using my board and core for a long time, but yesterday I got a
problem when tried to boot by dnw:
Copy linux kernel from 0x00060000 to 0x30008000, size = 0x00500000 ... done
zImage magic = 0x016f2818
Setup linux parameters at 0x30000100
linux command line is: "noinitrd root=/dev/mtdblock3 init=/linuxrc
console=ttySAC0"
MACH_TYPE = 1999
NOW, Booting Linux......
Uncompressing
Linux...........................................................................
................................................................................
................................
crc error
-- System halted
Then, I tried to backup the info on core, and then I found another problem,
that is possible related to the first error:
Enter your selection: u
Backup Information:
Start Addr : 0x0
End Addr : 0x10000000
bBackupOOB : 1
bCheckBad : 1
dwBackupTotalLen : 0x10800000
dwReservedBlks : 28
dwEPInPktSize : 32
=============== USB Backup Start ==============
Error: can't receive data from the USBD, for mtd info
=============== USB Backup Failed err:284 ============
Anyone has similar problem, or even know how to solve?
I don't have any idea of how recover this core.
Thanks in advance.
