Hi, I'm operating on an at91rm9200-based board. My AT91RM9200 board base on Flavio Ribeiro's sbc. After I sucessfully write and run loader to/from dataflash, I try to make u-boot work . I apply DataFlash boot patch (http://www.ime.usp.br/~fr/sbc/software/cmd_bootm.patch) for u-boot 1.1.2 and using gcc3.3.4-cross tool chain (install following this instructions on debian : http://people.debian.org/~debacle/cross/) to build.
I have problem w/ renaming short-load-bytes http://www.google.com/url?sa=t&ct=res&cd=1&url=http%3A%2F%2Fgcc.gnu.org%2Fml%2Fgcc-patches%2F1999-11%2Fmsg00649.html&ei=8z7ZROb-Mp_isAKOnujfCQ&sig2=o6autVRiFtph0PLakcM8oQ to alignment-traps on gcc3.3.4 ( http://www.google.com/url?sa=t&ct=res&cd=1&url=http%3A%2F%2Fgcc....)
To resolve it, I modify PLATFORM_RELFLAGS += -fno-strict-aliasing -fno-common -ffixed-r8 \ -mshort-load-bytes http://www.google.com/url?sa=t&ct=res&cd=1&url=http%3A%2F%2Fgcc.gnu.org%2Fml%2Fgcc-patches%2F1999-11%2Fmsg00649.html&ei=8z7ZROb-Mp_isAKOnujfCQ&sig2=o6autVRiFtph0PLakcM8oQ -msoft-float to PLATFORM_RELFLAGS += -fno-strict-aliasing -fno-common -ffixed-r8 \ -malignment-traps -msoft-float to on u-boot-1.1.2/cpu/at91rm9200/config.mk
After that, I get uboot.bin
But when i try to write uboot.bin to flash and start, i have error on terminal : Dataflash read successful: Starting U-boot...
and nothing happend, may be my board is hang...
Where am I wrong? Some one have any suggested for me ?
Thank you for your help in advance,
nm.
