It seems like default factory partition has been erased as per erase command executed so far..Only Boot loader partition is remained as it is.
But now we have to flash Kernel and File System as seperate image or combined sysfc upgrade image from provided boot loader but some how it seems like cp.linux command is not working or getting wrong address or don;t know exact load address because cp.linux command is return within one or less second after executing it
So, Don;t know like where exectly issue is like boot loader issue or memory address issue or loading address issue..
We have checked SPI commands as well but seems to be no any proper support or not working. Then we have dig into boot loader source code and found that option 0 is disabled to showcase into help of image flash loading option.
So, We have added and used that option which is working fine to update sysupgrade image into SPI Flash Memory
Thanks for providing support and help for the same.
Which option you are usuing to upload the firmware from uboot
There is one hidden option to upload the firmware. Instead of going in u-boot mode you can select the option 0, and directly select the file and upload the firmware. Rest of the stuf will be done by u-boot itself.
