The additional debugging reports the controller is running and not reporting an error (which is in addition to the transfer descriptor reporting that it is also running without error). I'm not sure what is going on. Can you try disabling CONFIG_MALLOC_UPPERMEMORY and retry? -Kevin

It looks like the USB device is successfully identified and configured, but when sending the "inquiry" command to the drive behind the USB interface the connection halts. Not sure why that would be - it could be something with the controller, but it's odd that it happens with both the ohci and ehci controllers. If you boot to linux (using some other bootable device) what does 'lsusb' and 'lsusb -t' report? Have you tested with a different type of usb drive? -Kevin

Did you disable threads in seabios (either via the kconfig option or via the /etc/threads runtime option)? It's not recommended to disable threads, and the USB code is less capable of handling timeouts when threads are disabled. Can you retry (and send the log) with threads enabled. If that fails, can you also try disabling CONFIG_USB_EHCI in Kconfig and send that log as well. -Kevin

USB timeout on ALIX.2C2 (CS5536)
by Евгени Димитров 05 Jan '17

Hi, I'm testing Coreboot with SeaBIOS as payload on my old Alix.2C2. When trying to boot from an USB device I get the following error: Searching bootorder for: /pci@i0cf8/usb@f,5/storage@2/*@0/*@0,0 Searching bootorder for: /pci@i0cf8/usb@f,5/usb-*@2 ehci_send_pipe qh=0x000ecf00 dir=0 data=0x00006cf9 size=31 ehci_send_pipe qh=0x000ecf80 dir=128 data=0x00006dc4 size=36 ehci_send_pipe qh=0x000ecf80 dir=128 data=0x00006cec size=13 WARNING - Timeout at ehci_wait_td:516! ehci pipe=0x000ecf80 cur=00000000 tok=00000000 next=6b40 td=0x00006b40 status=d0d80 USB transmission failed Unable to configure USB MSC drive. phys_free f6030 (detail=0x0f7688a0) Unable to configure USB MSC device. Google found a thread from 2012 [1] where someone had the same problem with this particular chipset. Unfortunately he was unable to resolve the issue. Attached you will find the complete logs from both Coreboot and SeaBIOS. [1] https://www.coreboot.org/pipermail/coreboot/2012-October/071629.html

More than 9 boot devices
by Аладышев Константин 04 Jan '17

04 Jan '17

Is it possible in SeaBIOS to have working boot menu with amount of boot devices more than 9? I mean in this case we have boot device numbers with two digits, which is impossible to select. If I want to select string 12 and try to enter "12", SeaBIOS recognizes "1" and boot from device "1"...

[PATCH v2] serialio: Support for mmap serial ports
