Subject: [U-Boot-Users] u-boot -> Linux prompt assistance
Date: Mon, 20 Aug 2007 22:40:19 -0500 [thread overview]
Message-ID: <007701c7e3a4$ff339220$fd9ab660$@rr.com> (raw)
I have u-boot running and am currently working on the Linux prompt. I store
uImage at ffd00000. u-boot is at fff00000.
* The Freescale BSP for the MPC8360 was used for the base. u-boot
1.1.6 and Linux 2.6.19 are the versions selected and reported.
* u-boot is running at the prompt and seems stable for u-boot functionality.
* Enabling the 64M of DDR2 memory was quite an endeavor but it appears
stable today. Nothing shows up with the basic u-boot memory test, and there
are no crashes using the normal u-boot functions. i-cache is enabled. Memory
problems have not been fully ruled out. Any suggestions on how to validate
the memory better?
* Linux (~2.6.19) is compiled with no changes at this point.
Executing "bootm ffd00000" results in a transfer to Linux that (due to the
CodeWarrior USB TAP?) I can follow the code up to the RFI in head_32.S. It
looks like it is executing farther than that. I have attached a dump of the
memory found at log_buf. Also attached is System.map.
My interpretation of the stack dump suggests that start_here is successfully
executing in high memory and the crash is within MMU_init. The crashes that
follow would seem to be as much a result of this first problem.
Any suggestions or observations about this crash would be appreciated.
