This doesn't seem to be the manufacturer/device ID.

It seems to hang up the board for some reason. Ahh, unaligned 16bit access on ARM. Please give these commands another try: => mw.w ff800aaa 00aa => mw.w ff800554 0055 => mw.w ff800aaa 0090 => md.w ff800000 Cheers, Stefan -- DENX Software Engineering GmbH, MD: Wolfgang Denk & Detlev Zundel HRB 165235 Munich, Office: Kirchenstr.5, D-82194 Groebenzell, Germany Phone: (+49)-8142-66989-0 Fax: (+49)-8142-66989-80 Email: off...@denx.de _______________________________________________ U-Boot mailing list U-Boot@lists.denx.de http://lists.denx.de/mailman/listinfo/u-boot
