Hi, all. I downloaded flashrom from http://www.openbios.org/viewvc/trunk/util/flashrom.tar.gz?view=tar, also it was built correctly, when I scp it to an SIS530/SIS5595 board with debian-4.0r2, it just can't recognize my Winbond W49G002U EEPROM, here comes the verbose log:
Sis530:~# ./flashrom -c W49F002U Calibrating delay loop... OK. No coreboot table found. Found chipset "SIS5595", enabling flash write... OK. No EEPROM/flash device found. Sis530:~# ./flashrom -R flashrom r Sis530:~# ./flashrom --version flashrom r Sis530:~# ./flashrom -V -r Calibrating delay loop... 59M loops per second. OK. No coreboot table found. Found chipset "SIS5595", enabling flash write... OK.

After quick reading of your source code, I saw this probing function: int probe_jedec(struct flashchip *flash) { volatile uint8_t *bios = flash->virtual_memory; uint8_t id1, id2; uint32_t largeid1, largeid2;
/* Issue JEDEC Product ID Entry command */ *(volatile uint8_t *)(bios + 0x5555) = 0xAA; myusec_delay(10); *(volatile uint8_t *)(bios + 0x2AAA) = 0x55; myusec_delay(10); *(volatile uint8_t *)(bios + 0x5555) = 0x90; /* Older chips may need up to 100 us to respond. The ATMEL 29C020 * needs 10 ms according to the data sheet, but it has been tested * to work reliably with 20 us. Allow a factor of 2 safety margin. */ myusec_delay(40);
/* Read product ID */ id1 = *(volatile uint8_t *)bios; id2 = *(volatile uint8_t *)(bios + 0x01); largeid1 = id1; largeid2 = id2;
/* Check if it is a continuation ID, this should be a while loop. */ if (id1 == 0x7F) { largeid1 <<= 8; id1 = *(volatile uint8_t *)(bios + 0x100); largeid1 |= id1; } if (id2 == 0x7F) { largeid2 <<= 8; id2 = *(volatile uint8_t *)(bios + 0x101); largeid2 |= id2; }
/* Issue JEDEC Product ID Exit command */ *(volatile uint8_t *)(bios + 0x5555) = 0xAA; myusec_delay(10); *(volatile uint8_t *)(bios + 0x2AAA) = 0x55; myusec_delay(10); *(volatile uint8_t *)(bios + 0x5555) = 0xF0; myusec_delay(40);
printf_debug("%s: id1 0x%x, id2 0x%x\n", __FUNCTION__, largeid1, largeid2); if (largeid1 == flash->manufacture_id && largeid2 == flash->model_id) return 1;
return 0; }
Seems flashrom routing got 0xff, 0xff on largeid1, largeid2. Has anybody tested this routing on SIS530? Thanks.
Jun.
Hi,
please re-post to coreboot@coreboot.org, most flashrom guys are on that list.
Has anybody tested this routing on SIS530?
No idea, but there are many reasons why this might not work.
- Bug in the chipset-specific code.
- Some board-specific init might be required (which is usually undocumented and non-trivial to find out).

Thanks, I will do it right now.
