From mboxrd@z Thu Jan 1 00:00:00 1970 From: Alfred Manheim Date: Mon, 20 Aug 2007 22:40:19 -0500 Subject: [U-Boot-Users] u-boot -> Linux prompt assistance Message-ID: <007701c7e3a4$ff339220$fd9ab660$@rr.com> List-Id: MIME-Version: 1.0 Content-Type: text/plain; charset="us-ascii" Content-Transfer-Encoding: 7bit To: u-boot@lists.denx.de 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.
