I totally bricked mine and it wont even make it to load uboot. I have no output from the console and the led flash in the same pattern every few second.
I already tried to rebuild the flash by inserting the binary at the good place in the flash but to no avail.
Thanks or the links but after opening the c50 bin file in HxD, the fact that the flash is empty from h0 to h20000 tell me that there is no boot loader in the bin. And from what I can see it is that exactly what I am missing from my flash chip.
