Braswell FPS memory init problems
Dear coreboot community, I am experiencing problems with FSP Memory Init on Braswell SoCs. FSP Memory Init is not returning. I have following processors that fail: Celeron J3060 and Celeron J3160; both have the same issue. The platform has 1 SODIMM module on channel 0. I am feeding the UPD header with correct SPD, but still no luck. I have also tried FSP MR1 and MR2, but nothing works. Is anyone here more experienced with Braswell platforms? Could You give me some advices? Best regards, -- Michał Żygowski Embedded Systems Engineer http://3mdeb.com | @3mdeb_com
Hi Michal, We have implemented coreboot on Braswell SoC (Pentium N3170) using SPD. Did you verify the UDP fields: PcdMemoryTypeEnable, PcdMemorySpdPtr PcdMemChannel0Config and PcdMemChannel1Config? Do you have some coreboot/FSP logging?

Hi Frans,

Did you verify the UDP fields: PcdMemoryTypeEnable, PcdMemorySpdPtr PcdMemChannel0Config and PcdMemChannel1Config?
These are settings I use in devicetree.cb: register "PcdMrcInitTsegSize" = "8" # SMM Region size in MiB register "PcdMrcInitMmioSize" = "0x0800" register "PcdMrcInitSpdAddr1" = "0xa0" register "PcdMrcInitSpdAddr2" = "0xa2" register "PcdIgdDvmt50PreAlloc" = "1" register "PcdApertureSize" = "2" register "PcdGttSize" = "1" register "PcdDvfsEnable" = "0" register "PcdCaMirrorEn" = "1" Secondly, using common Intel SoC SMBus block implementation, I retrieve SPD from DIMM and pass it to PcdMemorySpdPtr. Then setting PcdMemChannel0Config to 1 (soldered down memory) and PcdMemChannel0Config to 2 (DIMM disabled, because only the first channel is populated). PcdMemoryTypeEnable is left the default to 0 (DDR3) which should be correct.
Do you have some coreboot/FSP logging?

Hi Michal, Your logging seems to be correct. Any different behavior when specifying channel 0 as SPD and have FSP using DIMM spd data? Another suggestion is using debug version of FSP.

Hi Michal,
We have implemented coreboot on Braswell SoC (Pentium N3170) using SPD.
Did you verify the UDP fields: PcdMemoryTypeEnable, PcdMemorySpdPtr PcdMemChannel0Config and PcdMemChannel1Config?
Do you have some coreboot/FSP logging?

Dear coreboot community,
I am experiencing problems with FSP Memory Init on Braswell SoCs. FSP Memory Init is not returning. I have following processors that fail: Celeron J3060 and Celeron J3160; both have the same issue.
The platform has 1 SODIMM module on channel 0. I am feeding the UPD header with correct SPD, but still no luck. I have also tried FSP MR1 and MR2, but nothing works.
Is anyone here more experienced with Braswell platforms? Could You give me some advices?
Best regards,

Hi Frans, Thank You for response. Yes, I have also tried setting Channel Config to 0 (DIMM installed), but it does not work either. I have also been playing with CA mirroring and DVFS, but results are the same all the time. Debug FSP? Is such binary available anywhere? Could You point me please where to get it? Best regards, Michał On 01.02.2019 11:38, Frans Hendriks wrote:
Hi Michal,

Another suggestion is using debug version of FSP.

Hi Frans,
These are settings I use in devicetree.cb:
register "PcdMrcInitTsegSize" = "8" # SMM Region size in MiB register "PcdMrcInitMmioSize" = "0x0800" register "PcdMrcInitSpdAddr1" = "0xa0" register "PcdMrcInitSpdAddr2" = "0xa2" register "PcdIgdDvmt50PreAlloc" = "1" register "PcdApertureSize" = "2" register "PcdGttSize" = "1" register "PcdDvfsEnable" = "0" register "PcdCaMirrorEn" = "1"
Secondly, using common Intel SoC SMBus block implementation, I retrieve SPD from DIMM and pass it to PcdMemorySpdPtr. Then setting PcdMemChannel0Config to 1 (soldered down memory) and PcdMemChannel0Config to 2 (DIMM disabled, because only first channel is populated). PcdMemoryTypeEnable is left default to 0 (DDR3) which should be correct.
Here are the logs from Celeron J3160 (I have applied few of Your patches locally, C_ENV_BOOTBLOCK and FSP MR2 support):

Hi Michal, In coreboot 3rdparty package release version is available only. The FSP debug is not available in public. I can't help you with FSP debug in this public community, due too (Intel) license restrictions. If interested in assistance, you can contact us for engineering services.

Hi Michal,
We have implemented coreboot on Braswell SoC (Pentium N3170) using SPD.
Did you verify the UDP fields: PcdMemoryTypeEnable, PcdMemorySpdPtr PcdMemChannel0Config and PcdMemChannel1Config?
Do you have some coreboot/FSP logging?
Best regards, Frans Hendriks Eltan B.V.

Dear coreboot community,
I am experiencing problems with FSP Memory Init on Braswell SoCs. FSP Memory Init is not returning. I have following processors that fail: Celeron J3060 and Celeron J3160; both have the same issue.
The platform has 1 SODIMM module on channel 0. I am feeding the UPD header with correct SPD, but still no luck. I have also tried FSP MR1 and MR2, but nothing works.
Is anyone here more experienced with Braswell platforms? Could You give me some advices?
Best regards,
