Hi,

I am porting SEL4 on RISCV FPGA. I am stuck midway in the kernel elf loader.

The function stuck is memcpy. I have added prints and I am not progressing after the last memcpy call in unpack_elf_to_paddr(). All kinds of input appreciated.

Function under review: *static void unpack_elf_to_paddr(void *elf, paddr_t dest_paddr)*

/* Parse size/length headers. */ dest_vaddr = elf_getProgramHeaderVaddr(elf, i); data_size = elf_getProgramHeaderFileSize(elf, i); data_offset = elf_getProgramHeaderOffset(elf, i);

/* Load data into memory. */

* memcpy((char *)dest_vaddr + phys_virt_offset,* * (char *)elf + data_offset, data_size);* * printf("loaded data into memory \n"); -----> Stuck Here !* }

}

*Can anyone give me a clue on whatsoever to check here ? **It worked perfectly in spike simulation.*

*RISCV FPGA configuration* - It supports IMAFD. It has already booted linux. Kernel is loaded at physical address 80 million.
