Hi every one.
I have made a typo mistake, it cause the big problem with me.
I want to delete a partition with command sf erase 0x580000 0x1600000
However i put the wrong number : 58000 instead of 580000.
And now my router cannot boot any more:

B -    853895 - Error: CDT is not programmed
B -    857743 - Boot error ocuured!. Error code: 302a 

Could anyone please help me how to recovery the Uboot?
Thank you very much

Hi, you could try to extract the uboot from the original firmware with dd. After this you can write it with a jtag device back to the flash.
