Hi, I am using a BF537 EZ kit lite board and I am using uClinux. However I am having some problems with flashing the uboot. I have followed the steps found in the quick start guide and the uboot loading guide. I haved reached the part where I am able to copy the u-boot.bin file to the board and into the flash but when I reset the board it seems that the u-boot is not saved to the flash. I have successfully done installing and flashing the u-boot to the board, but when I did it again after erasing the flash memory and starting from the beginning, it won't work the second time around. I'm really wondering why it worked the first time but not the second time?
