Hi
I have a telescope motor control board with Linux OS I'm attempt to update firmware but failed, when power back on can't boot to the menu page only can boot to Update firmware again via Mini Sd card. How can i repair this boot loader or re-flash it? System consist of following chip CPU ADSP-BF531 sbstz400, Nand Micron 29F2g08AACWP, Exilinx XC2C256. You can look at PIctures.
Thank you
