If you don't have any code on the board then I can't think of how to write to the flash unless you have a JTAG device. I use a BDI2000 to do precisely what you're doing: write U-boot into virgin on-board flash on a design derived from the lite 5200.
The significance of the debugger is that you need something that can drive the microcontroller via the JTAG port and control the flash device write intricacies. Pre-programming your flash device is another option. -----Original Message----- From: [EMAIL PROTECTED] [mailto:[EMAIL PROTECTED] On Behalf Of Albrecht Dreß Sent: Tuesday, July 22, 2008 1:57 PM To: LinuxPPC Embedded Subject: [OT] write flash on MPC5200 board via jtag Hi, sorry for a somewhat off-topic question... I want to design a mpc5200b board which is roughly derived from Freescale's 5200B Lite demo. Obviously, I have the problem to initially write u-boot into the boot nor flash. I believe this would be possible using the jtag/bsm interface (is that true?). Can you recommend any good hardware and software solution for that, if possible running on linux (OSS?)? I don't need a "real" debugger (maybe an interface to gdb), just something to write the flash, so u-boot comes up. Thanks for any help, Albrecht. _______________________________________________ Linuxppc-embedded mailing list [email protected] https://ozlabs.org/mailman/listinfo/linuxppc-embedded
