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.
