Re: [coreboot] X201i RAM upgrade not working

[Mono]

Hallo Ron and Vladimir,

it seems the following behaviour is reproducible on my machine:

Boot 1: 1 DIMM installed in slot 0
    poweron, login, poweroff --> OK
        console output: 01_x201i_1DIMM_poweron_login_poweroff

Boot 2: 1 DIMM installed in slot 0
        poweron, login, flash, reboot, login, poweroff --> OK
        console output: 02_x201i_1DIMM_poweron_login_flash_reboot_login_poweroff
        note: reboot was done because after flashing poweroff hangs but reboot works

-->Add the second RAM module

Boot 3: 2 DIMMs installed
        poweron --> FAIL
        poweroff with the power button
        console output: 03_x201i_2DIMM_poweron_fails_powerbuttonoff

Boot 4: 2 DIMMs installed (this is just a second try)
        poweron --> FAIL
        poweroff with the power button
        console output: 04_x201i_2DIMM_poweron_fails_powerbuttonoff_v2

-->Remove the first RAM module

Boot 5: 1 DIMM installed in slot 1
        poweron, login, poweroff --> OK
        console output: 05_x201i_1DIMM_slot1_poweron_login_poweroff

-->Re-install the first RAM module

Step 6: 2 DIMMs installed
        poweron, login, poweroff --> OK
        console output: 06_x201i_2DIMM_poweron_ok_login_poweroff

I do not know why it fails, the last log message is:
Couldn't discover DRAM timings (3)

the logs are attached to this email.

with best regards
Mono

X201i RAM upgrade not working

[ron minnich]

I'm still convinced this is an issue with the code, not the insertion
of the DIMMs.

Are the DIMMs identical w.r.t. timing? Are you always plugging the
same DIMMs into the same slots, or did you try swapping them around?
