After the serial console was up I used printf-like debugging. And before that point I could live quite good with simple BDI commands. Whether source level debugging is possible with BDI2000? Also tell me what toolchains need to be used. Is ELDK supports? I don't know. I used a toolchain which I build myself using crosstools-ng (see http://freshmeat.net/projects/crosstool-ng/) Whether the video driver is available on u-boot ?

Hi Stefan, I am getting Machine check exception when my video driver is initializing. When i searched the net i found that you also faced the same kind of problem. I have mentioned the VIDEO_IO_OFFSET as 0xf000. This address is nothing but CONFIG_SYS_PCI1_IO_VIRT which is mentioned on my config file.

[U-Boot] Regarding MPC8640D second core initialization
Hi denx, I am using 2009-06 u-boot for MPC8640D based board. i just want to know whether the second core of MPC8640D is kicked off automatically or will it required by the user to kick. Also if am enabling the CONFIG_MP macro and CONFIG_NUM_CPUS as 2, then the reset command of the target is not working(means board is getting hanged). I have mentioned the value of CONFIG_SYS_SCRATCH_VA as 0xf500. Kindly suggest me what might be the error. Thank you, T. ___ U-Boot mailing list U-Boot@lists.denx.de http://lists.denx.de/mailman/listinfo/u-boot

[U-Boot] Regarding Reset command.
Hi kumar, We are having QUAD MPC8640D based System on which all the processors are sharing the same boot code which is residing on the 32bit boot flash memory. i don't find any problem with this. But i just want to know whether it will create any problem. My configuration is Processor 1 will boot first and it will kick the P2,P3,P4 from Processor 1 with help of Glue logic. One more clarification regarding fsl_pci_config_unlock() function. Where can we use this function ? On the datasheet it was mentioned that the Endpoint should use this bit to allow the inbound configuration accesses of endpoint.

Hi all, I am in bit of peculiar problem on booting linux kernel on my MPC7448-TSi108 based custom board. I am using u-boot 1.3.4 which was compiled on ELDK- 4.0. when i use bootp command to download the kernel image from the tftp server that was already working with other custom boards the kernel is not getting downloaded but if i am setting it to another environment variable i.e set ideboot bootp and try to boot using run ideboot this time the kernel image file is getting downloaded. kindly give me suggestion on this. i don't have any clue on what is happening ? The host system what ever i used for compilation is also same. Regards, T. ___ U-Boot mailing list U-Boot@lists.denx.de http://lists.denx.de/mailman/listinfo/u-boot
