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
