This section details how to run coreboot on the Supermicro X11SSH-TF.

Required proprietary blobs

Flashing coreboot

The board can be flashed externally using some programmers. The CH341 was found working, while Dediprog won’t detect the chip.

For more details have a look at the flashing tutorial.

The flash IC can be found between the two PCIe slots near the southbridge: ../../_images/x11ssh_flash.jpg


This board has an ASPEED AST2400, which has BMC functionality. The BMC firmware resides in a 32 MiB SOIC-16 chip in the corner of the mainboard near the AST2400. This chip is an MX25L25635F.

Known issues

  • Intel SGX causes secondary APs to crash (disabled for now).
  • Tianocore doesn’t work with Aspeed NGI, as it’s text mode only.
  • SMBus / I2C does not work (interrupt timeout)

Tested and working

  • USB ports
  • M.2 2280 NVMe slot
