Re: [SeaBIOS] USB-to-SATA bridge conflicts with USB boot flash drive
Hello!
I don't know how to provide an example for QEMU for this issue...
Anyway, I tried to debug more and have found out that the problem seems to be
in "scsi_drive_setup" (src\hw\blockcmd.c) function:
int scsi_drive_setup(...) {
ret = scsi_is_ready();
if (ret) {
dprintf(1, "scsi_is_ready returned %d\n", ret);
return ret;
}
...
}
When HDD is not present on the USB-to-SATA bridge, "scsi_is_ready" function
returns "-1" and this causes problems to USB flash drives on ports greater than
USB-to-SATA bridge USB port.
For now, I've simply replaced code above with version with hardcode check:
ret = scsi_is_ready();
if (ret) {
dprintf(1, "scsi_is_ready returned %d\n", ret);
if (!strcmp(product, "TUSB9261")) {
dprintf(1, "Skip TUSB9261 USB-to-SATA bridge with no devices\n");
return 0;
}
return ret;
}
This, of course, is not a full solution, but it works for my case. I hope my
info will help and someone with better understanding of SeaBIOS will come up
with a full solution.
Best regards,
Aladyshev Konstantin

Without looking at the code, can you come up with an example for QEMU
to reproduce this?
Kind regards,

not need to be online.

[SeaBIOS] USB-to-SATA bridge conflicts with USB boot flash drive
Hello! I use coreboot+SeaBIOS bundle on custom motherboard with Intel Haswell i7 and Lynxpoint-LP chipset and I've come to a strange issue with USB-to-SATA bridge TUSB9261 (http://www.ti.com/product/TUSB9261). In my experiments I plug HDD to one USB port, and USB boot flash drive to another USB port. Everything works fine when HDD is present on USB-to-SATA bridge. SeaBIOS displays both devices in its boot menu. But if HDD is not present and if USB boot flash drive is plugged to a port greater than USB-to-SATA bridge port, SeaBIOS doesn't see flash drive as bootable device. In this case I see in log messages similar to this: """ Searching bootorder for: /pci@i0cf8/usb@1d/hub@1/storage@7/*@0/*@0,0 Searching bootorder for: /pci@i0cf8/usb@1d/hub@1/usb-*@7 ehci_send_pipe qh=0x000eab80 dir=0 data=0x6b79 size=31 ehci_send_pipe qh=0x000eab00 dir=128 data=0x6c98 size=36 WARNING - Timeout at ehci_wait_td:516! ehci pipe=0x000eab00 cur=69c0 tok=80240d80 next=1 td=0x69c0 status=240d80 USB transmission failed Unable to configure USB MSC drive. phys_free f4950 (detail=0x7f6c13c0) Unable to configure USB MSC device.
