Hello!
I'm trying to port coreboot to my ga-780t-d3l-rev4.0 mainboard
It has AM3+ socket, fam15h cpu, 760G (RS780L) and SB710
And I have 2 problems, running coreboot:
1) "AMD_CB_EventNotify: ERROR: HT_EVENT_NCOH_DEVICE_FAILED: node 0 link 0 depth: 0 attemptedBUID: 1"
i've added some trivial printk debug and get
cpuSetAMDMSR done Enter amd_ht_init Fam15 northbridge interface secBus = 0 currentPtr = 0x0 Found device 0x96001022 Total links = 0 Searching of next capabilities at 0x0 currentPtr = 0xC4 Writing BUID=0x1 to [20:16] of 0xC4 Read 0x0 from 0x000080C4, bits [20:16] AMD_CB_EventNotify: ERROR: HT_EVENT_NCOH_DEVICE_FAILED: node 0 link 0 depth: 0 attemptedBUID: 1 AMD_CB_EventNotify: INFO: HT_EVENT_NCOH_AUTO_DEPTH: node 0 link 0 depth: 255 Exit amd_ht_init cpuSetAMDPCI 00 done
2) second problem, that coreboot finish booting at
"Waiting for predriver calibration to be applied..." when memory initialization
After this system writes, that BIOS checksum is incorrect and restores original bios from backup
