I am using http://urjtag.org/ UrJtag to do accomplish this. I have used it with both a Wiggler clone and an Altera UsbBlaster as the physical JTAG interface on both a Linux and Windows (cygwin) host. The only problem is that this approach is very slow, so I wrote a small (~8kb) "bootstrap" program which is first put into flash. This small program then handles programming u-boot to flash over a serial interface. Once u-boot is in place, I use it to program the rest of flash.
Some JTAG tools actually place a small application in the target devices ram, then this application allows much faster programming of an attached flash device. This requires more information about the COP/BDM interface than is published in the MPC5200B user manual or data sheet. I haven't used the Abatron tools, so maybe they do this. In the case of UrJtag, it is simply fiddling with bus signals using boundry scan, so it is excruciatingly slow. -WITTROCK -- View this message in context: http://www.nabble.com/-OT--write-flash-on-MPC5200-board-via-jtag-tp18596887p18609501.html Sent from the linuxppc-embedded mailing list archive at Nabble.com. _______________________________________________ Linuxppc-embedded mailing list [email protected] https://ozlabs.org/mailman/listinfo/linuxppc-embedded
