My board config is based on the existing P2020RDB board. The code faults very early with an instruction TLB error when transitioning from the boot page (0xfffff000) to the flash's address space (0xeffff000). The TLB has the same valid entries that U-Boot has setup at the corresponding point in the code (at the end of create_init_ram_area). I have tried to compare start.S with its U-Boot cousin but alas, my PPC assembler fu fails me. Are there any differences between the E500 cores in the P1020 vs. P2020 that must be taken in to consideration in start.S? -- Thanks - wkz _______________________________________________ barebox mailing list barebox@lists.infradead.org http://lists.infradead.org/mailman/listinfo/barebox
