ectool misusage in autoport
by Iru Cai Aug. 25, 2015

Aug. 25, 2015

Hi, I'm trying to use autoport to port coreboot to a machine. However, when I look at the logs generated by: ./autoport --input_log=logs --make_logs --coreboot_dir=../.. I saw in logs/ectool.log: ../ectool/ectool: invalid option -- 'a' usage: ../ectool/ectool [-vh?Vidq] [-w 0x<addr> -z 0x<data>] So the autoport program doesn't make use of ectool, and it needs some fixing.

I don't know C but I'll try to figure out how to do that, and then maybe ask about increasing ELOG size beyond 4 digits once I have something working. > > Also, I assume you mean cbmem console when referring to cbmem above? > Yes. Me and terminology don't get on though I try. ;) What I would be thinking of doing is using this as a poor-man's debug - reading the ROM containing ELOG using an external programmer and using a hex editor to view it (if that's possible). Thanks again. -John.

Hi Guys, This may be a daft question technically, but is there some way event logging could be subverted to store cbmem output? -John.

Swapping Ctrl and Fn on X200
by Danny Milosavljevic Aug. 23, 2015

Aug. 23, 2015

Hi, I'm trying to swap Ctrl and Fn keys on the X200 (with libreboot). For this I made sure that nvram is not wiped on reboot, then set fn_ctrl_swap = Enable using nvramtool. This doesn't swap Fn and Ctrl for some reason. For comparison, as soon as I change "trackpoint = Enable" to "trackpoint = Disable", the trackpoint stops working - so I know that the nvram is not completely ignored. So next I found http://forum.notebookreview.com/threads/fn-ctrl-swap-on-all-lenovo-laptops-… , unpacked it and compared it to Lenovo's original. The changes are in: "6DET64WW/$01B9000.FL2" (47 Byte differ, starting at decimal offset 2713050 but not a continuous range - the last change is right before decimal offset 2818048), "7XET64WW/$01B9100.FL2" (47 Byte differ, starting at decimal offset 2713050 but not a continuous range - the last change is right before decimal offset 2818048). If I want to both use libreboot and swap Fn and Ctrl (so Ctrl is to the left), how do I get these changes into it? With kind regards, Danny
