hello,
I have damaged the bootloader of mine wnr854t, with chip marvell feroceon 88f5181.
Now, i am using wiggler cable (buffered) a + openocd for re-flashing, the problem is that continuous to receive errors.
Where mistake?
thanks

using the patched openocd code you need to run the command
flash probe 0
(you should see)

hi,
thanks for the interest. In previous log files of U-Boot:
Marvell>> flinfo
Bank # 1: INTEL 28F640J3A (64 Mbit)
Size: 8 MB,Bus Width: 2, device Width: 2.
Flash base: 0xff800000,Number of Sectors: 64 Type: REGULAR.
therefore in the rows of openocd.cfg I have inserted:
#target <type> <endianness> <startup mode> <chainpos> <variant>
target feroceon little reset_init 0
# driver addr size chip_width bus_width options
flash bank cfi 0xff800000 0x800000 2 2 0
Now executing the command:
> flash protect_check 0
value captured during scan didn't pass the requested check: captured: 0x0f check_value: 0x01 check_mask: 0x0f
in_handler reported a failed check
... ....
value captured during scan didn't pass the requested check: captured: 0x0f check_value: 0x01 check_mask: 0x0f
in_handler reported a failed check
value captured during scan didn't pass the requested check: captured: 0x0f check_value: 0x01 check_mask: 0x0f
in_handler reported a failed check
JTAG error while reading cpsr
auto_probe failed -900
Syntax error:
protect_check check protection state of sectors in flash bank <num>
>
but it is possible to restore U-Boot?
thanks
