If you increase SDHCI_POWER_ON_TIME instead, does that also work? -Kevin

Attached is the simplified patch. Hopefully someone can test other cards. I'm interested to know if 128+GB and 16GB works. Chris

Like I said though, still testing but looking good. Interesting. Can you test if it is the msleep() that is needed, or if it is the second initialization that is needed? (Or both?) Thanks, -Kevin

I know it has been months but I just had an idea that seems to fix this issue. I still need to test for some time to make sure but so far it is working fine. What I did is simply add a delay before the SD card is initialized. The attached patch takes a brute force approach and will attempt to initialize multiple times. However, so far it has never had to attempt the initialize more than once. That little "msleep(5)" before setting up the card seems to be all that is needed. Like I said though, still testing but looking good. Chris

Fix this by changing length to a u32. Thanks. I committed this change. -Kevin

Excuse me, is there some case of successful attempts on Windows 10? Or just some technical knowledge has not really test? Could you provide me some technical docs?

Still vTPM 2.0 for win 10 problem， I downloaded the latest qemu source from git, the version is V3.0.50. I think this is the latest code of qemu upstream. I also downloaded seabios upstream and bulid it with tpm2 support.

vTPM 2.0 is recognized as vTPM 1.2 on the Win 10 virtual machine with seabios
by 汤福 23 Aug '18

23 Aug '18

Hi, I want to use the vTPM in a qemu Windows image. Unfortunately, it didn't work. First, the equipment: TPM 2.0 hardware CentOS 7.2 Qemu v2.10.2 SeaBIOS 1.11.0 libtpm and so on My host is centos 7.2 with the TPM 2.0 hardware and qemu v2.10.2. I make the libtpm and seabios with ./configure, make and so on. I checked seabios with make menuconfig the TPM setting. It is enabled tpm by default. Eventually, all works without errors. I start the Widnows 10 image with: qemu-system-x86_64 -display sdl -enable-kvm -m 2048 -boot d -bios bios.bin -boot menu=on -tpmdev cuse-tpm,id=tpm0,cancel-path=/dev/null,type=passthrough,path=/dev/tpm0 -device tpm-tis,tpmdev=tpm0 win10.img First it looks all fine. Windows 10 booted up but the vTPM was recognized as TPM 1.2 instead of TPM 2.0 in device manager. I open the tpm Manager with tpm.msc but get error with No compatible TPM found. If I use vTPM in a qemu linux image, everything gose well. So, what could be the problem? Thanks

I have acer c720 with seabios and ubuntu both wifi and lan no longer work since then I do not have the network able to flash the seabios. is there a ROM version that can be downloaded but flash without a network?

Boot failed: could not read from CDROM-Blu-ray Disc
by CarlosGonzalez 22 Aug '18

22 Aug '18

Hello there I am using seabios with coreboot, but I have an issue on booting CD-ROM. I have a CD-ROM-Blu-ray-Disc the problem is when is booting seabios this is showing an error message on CD-ROM then I need fix that ugly message. Seabios detect my CD-ROM y booting as well but I do not know why is showing the "failed to learn CD_ROM". Will nice fix the issue Thanks . ##this screenshot is when the cd-driver NOT have a cd-image inserted## [20180714_172630.jpg] ##this screenshot is when the cd-driver have a cd-image inserted## [20180822_124130.jpg]

Re: [SeaBIOS] acer c720 microcode

I think you're conflating a lot of different things here. I'm assuming you are running a 3rd party firmware on your device which boots SeaBIOS as its payload. Wifi/LAN not working are unlikely to be firmware related, so flashing something else isn't going to help. The 'update microcode' message is just that, Linux is updating your microcode as part of booting. There's no problem which needs fixing. Assuming the problem you are trying to solve is lack of network connectivity on your device, the best resource for that is going to be some place that deals with hacking Chromebooks, like https://www.reddit.com/r/chrultrabook/. But it's not a SeaBIOS issue in any way.
