i want to test the device tree loading stuff in qemu. I don't see a way to set the r5 register on startup via command line in qemu.
void bsp_fdt_copy(const void *src) { const volatile uint32_t *s = (const uint32_t *) src; im tempted to either hard code the src location rather than passing it in via r5 or add a check if the passed in value is null then use a hard coded address. if(src == 0x0) { s = BSP_START_COPY_FDT_ADDRESS; } qemu can then take a address for the device tree file and place it in the proper memory address -device loader,file=$DTB_FILE,addr=$BSP_START_COPY_FDT_ADDRESS,force-raw=true \ Does this seem reasonable or is there a way people are testing device tree support in qemu by setting the r5 register on startup? -- Sincerely, Sam Price _______________________________________________ devel mailing list devel@rtems.org http://lists.rtems.org/mailman/listinfo/devel
