Download for BIOS v4.6
I have a problem with the HPET and TSC timers in the latest BIOS version that we are trying to track down. We upgraded (hundred boards on 3.3) to the latest to start utilizing the iTCO functionality as the hardware was starting to crash regularly with GPF, and other low level hardware errors to have the hardware watchdog reboot it so we can still access or remote devices. Since we only see this problem in v5.0 BIOS hoping we can try 4.6 to see if the problem gets resolved, but we can't find the download available from the download site.
Click on the hyperlink below to download the BIOS v4.6 (UPA1AM46)
Please follow the steps below to safely downgrade to BIOS v4.6
1. Please refresh the BIOS down to BIOS v4.0 as download link https://downloads.up-community.org/download/up-squared-uefi-bios-v4-0/#
2. Upgrade BIOS to BIOS v4.6 (UPA1AM46)
Can you please describe better the issue and how to reproduce it?
We would like to review with our BIOS team if there is anything wrong with the latest release.

I appreciate the BIOS link. It appears to be an issue outside of the up2 board in our case and unrelated to the BIOS update. We did have a board not flash successfully, and is now unbootable. I have a working SPI programmer, and flashing software, but I am having trouble finding the CN22 connector available for the recovery flash. Do you know a compatible part number for the connector cable I can use to make a custom one?
The pitch of the CN22 is 1.27mm, so you need a female socket connector (6x2p) in 1.27mm, like the sample below
1.27mm straight female header connector
Or, you can choose to connect the SPI programmer to the SPI Chip via wire with hook, for example as below
