[U-Boot-Users] u-boot on EP8260 M 1.3
Hi all
I tried to replace the PlanetCore bootloader with U-Boot. I successfully (struggled and) erased the PlanetCore bootloader. I then programmed U-Boot into the FLASH (8 Mb) using CodeWarrior and WireTAP.
I used the standard (unmodified) image of U-Boot for the EP8260 compiled using the ELDK.
CodeWarrior reports that the u-boot image was successfully programmed. However, nothing appears on the monitor console after power-up. Even the LEDs stop glowing.
I also tried to restore the HRCW using the procedure given in the manual: - Keep RO2 shorted - Apply Power - Program the bootloader (U-boot image) - Remove power - Remove the short
All in vain. The board still does not show anything on the console. Is U-boot running? How do I proceed from here?
I am fairly new to U-boot, so any help would be appreciated.
Thanks and regards, Nishant

Is this configuration valid for revision M 1.3?

Did you read the flash manually to verify that u-boot was written ok and that the HRCW was written correctly? More importantly, are you writing both of these things to the correct location?
I also tried to restore the HRCW using the procedure given in the manual:
Doesn't the manual assume your are using PlanetCore to configure the HRCW via the PlanetCore command line utility? Did you take that into account?
