Re: [coreboot] Try to get Intel Atom based COMe-cXLi2 Kontron board running

These are not stupid questions at all. Have you considered getting an EM100? That would give you a little more debugging. A post card is about the single most useful thing to have in the early going, so you should probably get that before you go much further. Beep is a lot harder than it used to be. While simple code may work on Linux, there's a lot more going on under the hood, because the simple beep can be driven by a very complex audio pipeline. Beep may not be a good place to start. Here's a slightly bigger question: does it have to be an x86? Could it be ARM? Because here's a true story. I'm answering questions from some security researchers who *were* working on a haswell chromebook (Acer C720). Last week they realized that Intel was not going to make the blobs available for the memory startup (MRC) and the ME for haswell chromebooks. Those blobs are available for the sandy and ivybridge chromebooks, but nothing that came after. Result: all the researcher's work is moving to the Samsung ARM Chromeook because the ARM vendors tend to be a lot more helpful (save for AMD, nowadays; there are lots of unanswered questions there). I'm sad about that because Acer C720 is a great laptop and haswell is a great chipset, but what can you do? Note that the new Acer 13 is an ARM Tegra system that runs coreboot. So, just to be sure: it has to be an Atom? It's a much harder road than an ARM nowadays. ron

Try to get Intel Atom based COMe-cXLi2 Kontron board running
by Manuel Huber 18 Aug '14

Hello coreboot community, I'm currently trying to add support for the cXLi2 COM Express board from Kontron (I'm working for TTTech Automotive GmbH). On IRC, I have already talked to members of the coreboot community and started to prepare the new board. I'm basing my work on the iWave/iWRainbowG6 (which is quite different). Most important components are: - Processor: Intel Atom Z520PT - Chipset: Intel SCH US15WPT (Poulsbo) - Super-IO: Winbond W83627HG - BIOS flash chip: SST49LF008A Unfortunately, there was no output on the serial line and I haven't got a POST card yet. So I thought it should be easy to get the chipset to beep. I checked under Linux (using the vendor BIOS) and in the datasheet and it seems to be correct. I added the beep code to romstage.cc:main(). But nothing happened... I checked again, and thought that maybe, the boot process gets stuck earlier, so I rewrote the beep-code in ASM and added it just after entering protected mode (which seems to be pretty early...) -> but again, no sound. (under Linux both, the asm code, and the C-code work). Beep code: diff --git a/src/cpu/x86/32bit/entry32.inc b/src/cpu/x86/32bit/entry32.inc index f74e1b8..d46b883 100644 --- a/src/cpu/x86/32bit/entry32.inc +++ b/src/cpu/x86/32bit/entry32.inc @@ -52,6 +52,18 @@ __protected_start: /* Save the BIST value */ movl %eax, %ebp + /* Beep ! */ + movb $0xb6, %al + outb %al, $0x43 + movb $0xa9, %al + outb %al, $0x52 + movb $0x04, %al + outb %al, $0x52 + inb $0x61, %al + orb $0x03, %al + outb %al, $0x61 + movl %ebp, %eax + post_code(POST_ENTER_PROTECTED_MODE) movw $ROM_DATA_SEG, %ax ---------------------------------------------------------------------- 0xb6 => 10 11 011 0 Timer2 | Write LSB then MSB | Square Wave Output | binary ---------------------------------------------------------------------- So I guess I'm doing something completely wrong. I have to use an external flash programmer (DATAMAN-48Pro2) to actually program the flash chip since the SCH and my vendor bios image block access to the chip. So I can't use flashrom to program the device. The Dataman just loads the coreboot.rom image and write it to the memory. I'm currently just using the iWRainbowG6 code base directly (I though there that maybe I got my Kconfigs and Makefiles wrong)... (I have already created the new board and of course I want to prepare my code to be able to push it upstream if it ever works) However, using the original BIOS (which also takes 8192KB) and flashing it with the DATAMAN can boot. Is there something I'm forgetting, shouldn't the 'beep' work? Am I missing some initialization code? Sorry if my questions | assumptions are somehow stupid. I hope you can help me and point me in the right direction. Best regards, Manuel

Thanks :) Meanwhile I was able to boot qemu-armv7. It was all about memory map.

If you want I can commit above changes (after I figure out how to use gerrit and all that stuff). This of course mean that '-bios' option in qemu-system-arm should be used. One last questions which bootloader you will suggest to boot Linux kernel ? U-Boot ? Or maybe it is possible to boot it directly from coreboot ? Is there tutorial/manual how to do that ?

qemu-armv7: memcpy to ROMSTAGE_BASE
by Piotr Król 16 Aug '14

16 Aug '14

Hi all, during debugging of qemu-armv7 I found that coreboot performs memcpy to ROMSTAGE_BASE area. This is in src/arch/armv7/memcpy.S: 3: PLD( pld [r1, #124] ) 4: ldr8w r1, r3, r4, r5, r6, r7, r8, ip, lr, abort=20f subs r2, r2, #32 str8w r0, r3, r4, r5, r6, r7, r8, ip, lr, abort=20f bge 3b r0 at this moment (for qemu-armv7) is 0x10000 (ROMSTAGE_BASE). Is it ok that ROM area is used as storage during memory copying ? Shouldn't it be considered read only ? Am I missing something here ? Because coreboot execute from RAM this is not the problem but when I try to execute it from flash ('-bios' option) I'm unable to boot because qemu emulates flash as read only area. Is it ok to move ROMSTAGE_BASE to SRAM or this is violation of general rule ? Thanks, Piotr

nvidia/tegra build tool
by Isaac 15 Aug '14

15 Aug '14

The new nvidia/tegra124 support requires a build tool from NVIDIA called cbootimage (https://github.com/NVIDIA/cbootimage). I'm not sure of the best way to add support into coreboot so I'd like to get some feedback. Would it make sense to just add it into the util directory and build as needed?

You need to enable them. Please verify with the following command. $ grep TIMES .config CONFIG_COLLECT_TIMESTAMPS=y > http://pastebin.com/16LBAfBL Thanks. Could you please attach the files to save the work to create and cop- paste the contents manually? In my opinion paste bin services are only useful for IRC. For emails you should always paste directly or attach the content. Thanks, Paul PS: It’d be great if you opened a separate thread about your issue with `board_status.sh -u`. Thanks, Paul

As the change set #6535 [1] has been submitted, you do not need to do that anymore. Thanks, Paul PS: Did you report that issue to the list? It might have been fixed earlier if you had done that.
