I'm playing around with the am335x code now and have the sel4 test building but not working properly. If anyone else is interested in playing with this, let me know.
I have a question about the boot loader, I'm seeing:
if (UART_PPTR < kernel_info.virt_region_start) { printf("Jumping to kernel-image entry point...\n\n"); } else { /* Our serial port is no longer accessible */ }
is this necessary? It looks like init_boot_pd established a 1:1 mapping for all addresses lower than the kernel vaddr (which for me is 0xf0000000). Shouldnt the UART be accesible here?
I'm seeing the bootloader run up to mmu is turned on but nothing after that and trying to track down where the failure is happening. printf's after arm_enable_mmu are not working for me, and I don't understand if this is due to mmu bringup problems or something else.
By the way, I started a "#seL4" channel on freenode IRC.
