Dear (Embedded)-Kernel-Devs, I'm trying to build linux 2.6.34.1 for a AT91RM9200 target. The whole build process is successful because I get correct kernel images and also a uImage for U-boot. The U-boot version is 2010.08. I have build the whole system on a 64bit ubuntu machine. I use the latest buildroot to make the toolchain and etc. At this moment I have a openocd jtag dongle connected to my target for debug sessions. I have check that the machine id/type are correct. I have gotten those error messages of a unsupported target. I have resolved those errors. The target is self is a AT91RM9200 with 64MiB ram and 16MiB cfi flash. The boot args of u-boot are "console=ttyS0,115200n8 root=/dev/mtdblock0 rootfstype=jffs2 mem=64M". The problem is now when linux kernel is booting, nothing happens. --- U-Boot> bootm ## Booting kernel from Legacy Image at 21000000 ... Image Name: Linux-2.6.34.1robin9200v1.0 Image Type: ARM Linux Kernel Image (uncompressed) Data Size: 1811796 Bytes = 1.7 MiB Load Address: 20008000 Entry Point: 20008000 Verifying Checksum ... OK Loading Kernel Image ... OK OK Starting kernel ... Uncompressing Linux... done, booting the kernel. --- Here is stalls. With my jtag probe I can locate the problem. --- > halt target state: halted target halted in ARM state due to debug-request, current mode: Supervisor cpsr: 0x600000d3 pc: 0xc000af3c MMU: enabled, D-Cache: enabled, I-Cache: enabled > arm disassemble 0xc000af3c 0xc000af3c 0xeafffffe B 0xc000af3c --- This just loops at that address. Why does it that? You see that the mmu is enabled and the cpu has remapped the memory. Does someone have a clue what goes wrong? Here is the .config and board file. http://www.on8rth.be/wp-content/uploads/2010/09/dotconfig.txt http://www.on8rth.be/wp-content/uploads/2010/09/board-robin9200.c Thank you Robin Theunis ON8RTH -- To unsubscribe from this list: send the line "unsubscribe linux-embedded" in the body of a message to majordomo@xxxxxxxxxxxxxxx More majordomo info at http://vger.kernel.org/majordomo-info.html
