Hi all,
Hello,
I'm trying to boot a linux kernel image. It is about 2 MBytes. I used buildrom to generate the 4MB binary image (coreboot+linux) that I downloaded to Artec LCP Dongle flash. IIUC, to read the payload it is necessary to enable the 4MB window in LCP addressing space. To do that I modified cache_as_ram_main function in order to write 0xF4 to I/O port 0x88:
void cache_as_ram_main(void) { outb(0xF4, 0x88); ...
However it does not work: a) white LED on dongle is still off
See http://coreboot.org/viewvc?view=rev&root=coreboot-v3&revision=660 and do it in a similar place
b) coreboot prints:
Before VSA: do_vsmbios buf ilen 1011820 olen949065 buf 00060000 *buf 255 buf[256k] 255 buf[0x20] signature is ff:ff:ff:ff do_vsmbios: no vsainit.bin signature, skipping! After VSA: Graphics init... VRC_VG value: 0xffff Finding PCI configuration type. PCI: Sanity check failed pci_check_direct failed
I guess this isn't related to the dongle and it's 4MB mode, as that's just really useful post-BIOS at payload time, unless you are trying to fit the ROM into more than 1MB. But at a glance it seems like you don't have the VSA blob included in flash? Is this coreboot-v2 or coreboot-v3?
Anybody can help me?
