- unprotect and erase the hole flash.
- copy the latest u-boot.bin to flash
2.1 usb start 2.2 fatload usb 0:1 0xa0000000 u-boot.bin 2.3 protect off 0x0 0x3ffff
You mean protect off 0 0x40000 ? (0x3ffff makes no sense)
When i try to use the 0x40000 address i got the following message: Error: end address not on sector boundary
and flinfo shows all sectors are RO
2.4 erase 0x0 0x3ffff 2.5 cp.b 0xa0000000 0x0 $filesize 3 reset to look the u-boot is installed 3.1 see that CRC is bad (normal behavier couse no defaults are written) 3.2 savenv and powercyle 4. all fine 5. copy kernel image to flash 5.1 usb start 5.2 fatload usb 0:1 0xa0000000 uimage-2.6.35.9-toradex-pxa270v22b 5.3 protect off 0xc0000 0x47ffff 5.4 erase 0xc0000 0x47ffff 5.5 cp.b 0xa0000000 0xc0000 $filesize 6. check the uImage 6.1 iminfo 0xC00000 - OK 7. hard reset (power cycle)
Now comes the part that i dosen't understand The U-Boot loader sayes again that the CRC is bad and using default
values.
Did you not overwrite the env? The env is at 0x40000 in the flash.
Yep i did. That was the problme which Vasily and Rommel are pointed out.
