Here's the problem. There is caching of the DRAM configuration going on. So, a restart is not stateless. I would be happier if you could guarantee that the mrc cache is disabled, or never used, each time you change the dram setup (move DIMMs, whatever). Because from your earlier description it sou

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? ron -- coreboot mailing list: coreboot@coreboot.org http://www.coreboot.org

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, reboo

I don't think it's random at all. Vladimir can confirm, but if he is caching the RAM parameters, then this 'solution' will work for you until the next time you reflash coreboot, or change your dram type, at which point it will stop working. It's not a solid solution. ron -- coreboot mailing lis

I was not hot plugging them, but powering off and removing the battery as well during each change with the DIMMs. I absolutely don't know why it did not work before using the second slot separately. It might just have been random? greets Mono On Fri, Sep 05, 2014 at 01:57:36PM -0700, ron minnic

Or are you booting with the second slot full, powering off, loading both slots, and it works because of the MRC cache? On Fri, Sep 5, 2014 at 1:57 PM, ron minnich wrote: > On Fri, Sep 5, 2014 at 1:56 PM, Mono wrote: >> um, I tested the second slot separately as suggested by phcoder and after >>

um, I tested the second slot separately as suggested by phcoder and after that they work together too. thanks! On Fri, Sep 05, 2014 at 09:27:02PM +0200, Mono wrote: > Hallo all, > > Is anyone successfuly running the x201 port with two RAM modules installed? I > am using it (commit 8128a56c0ec7e

Hallo all, Is anyone successfuly running the x201 port with two RAM modules installed? I am using it (commit 8128a56c0ec7e147d4ad68e6ba55979e9ead25ae from Sep 18) for booting a x201i computer with only one RAM module (2GB). As soon as I insert a second RAM module (2GB) it does not boot anymore.
