Re: [coreboot] Coreboot 4.5: No early serial output
by Naveed Ghori 30 Mar '17

30 Mar '17

Fixed. Best I can tell it was due to a clean build as all the other parameters are the same. I had gone back to v4.4 to rebuild and check too, but the problem has persisted. Potentially to do with using .config from a different version of coreboot. But it works so no more investigation ☺.

What entity initializes serial port in Coreboot 4.4 (BYT FSP or Coreboot itself)? In which stage?

@Zoran: I tried flashing with the IFWI .bin file released by Intel, and the file I got after building coreboot and stitching. Both don't work. 2017-03-29 18:00 GMT+01:00 Zoran Stojsavljevic < zoran.stojsavljevic(a)gmail.com>: > > ...tried flashing SPI chip (Winbond W25Q128FW)... > > Flashing with what (context in question)? > > (we'll come later to INTEL stitching tool, I have good > perception/anticipation, developed for by INTEL) ;-) > > Thank you, > Zoran > > On Wed, Mar 29, 2017 at 1:29 PM, Toan Le manh <lemanhtoantb(a)gmail.com> > wrote: > >> I got the LeafHill CRB from Intel, tried flashing SPI chip (Winbond >> W25Q128FW) using BeeProg2C. >> However nothing worked.

The Status Code remained "0". Are you saying the flashing didn't work OR board doesn't boot after? If latter, did you select "Use IFWI stitching" ? Andrey

Sorry, this was badly articulated. The "thanks" was meant sincere. I had this on my TODO list for some time. I think we should (if not already done) extend ifdtool to toggle whatever bit is needed to run without ME firmware. And let people use that instead of building a new blob which only extends the list of entities you have to trust. Nico PS. Actually I think coreboot shouldn't handle these platform blobs at all. But that's even harder to convince people of ;)

Question about Intel HD graphics and FLR
by Joshua Pincus 29 Mar '17

29 Mar '17

Hi, After performing just an FLR (PCI function level reset) of a Gen8 Intel HD graphics device, there's no VGA output from the device, no matter what I try to do. I've had coreboot reset the graphics control register, VGA control, VGA display disable bit, etc. Has anyone seen anything like this? The only way I can get VGA restored is by performing a system-level reset. But I just want to do an FLR. Any ideas? Thanks, JP

Re: [coreboot] [flashrom] flashrom and MacMini 2009

I'll move this to coreboot :) Anyway, looking at coreboot, it supports not only the Macbook2,1 but also the Macbook1,1 and iMac5,2, all with nearly the same code. IMO, it's very likely that the Macmini2,1 matches one of them or comes close at least. So there wouldn't be much work on the software side. Before installing coreboot the first time, however, you should have a solution to flash your MacMini externally (i.e. with an extra flash programmer that can flash your BIOS/coreboot in case the machine doesn't boot any more). It's just too easy to brick a machine when trying a coreboot build that hasn't been tested before. It's not unlikely that you already have suitable hardware. Most single- board computers (RaspberryPi and the like) have a native SPI interface. Beside that you'd need some cables and either an SOIC clip matching your flash chip or a soldering iron. Nico

Out-of spec EC control codes
by Andrey Korolyov 29 Mar '17

29 Mar '17

Hi, while doing LPC examination for keyboard actions on Getac laptop few weeks ago, I noticed that the controlling sequence for backlight step has been put outside of an ACPI spec for no visible reason (therefore it is not possible to control backlight using unmodified ectool, for example). Sample step control sequence when Fn+Backlightxx is pressed looks like following: CT DT 0x80 0x17 // Reading 0x17 for current level, twice (why???) 0x80 0x17 0x86 0xff 0xf9 0x7f // Ok, now that`s weird, Why OEM-ing control sequences is necessary in there? 0x80 0x17 // Reading updated value I wonder if some people in list have touched simular kind of development, is there any real reason behind using non-standard control commands for EC? There *are* counterexamples in coreboot tree, but they are using very extensive control command set and stepping outside of spec looks reasonable. In my case, controller seemingly uses just as few handles as the spec suggests, but omits standard ones in favor of 0x85/0x86, could be there any practical reason for doing this?
