Revision as of 13:30, 11 May 2021

Due to an EOL the WIFI module this part is being replaced wit the Silex SX-SDMAC2832S+ starting with PCB revision F.

For users who do not use WIFI and write their own image, no action is required to support REV F boards.

For users with custom u-boot binaries this requires a u-boot change to support loading the new PCB revision device trees.

U-boot will now search for the device tree preferring a file with the -rev<pcbrev> in the file name. For example, on a quad core TS-7970 REV F, it will attempt to load these files in this order:

  • imx6q-ts7970-revf.dtb
  • imx6q-ts7970.dtb

Boards before REV F will not attempt to load the revf dtb files.

When using the older images which did not have the pcb rev in the device tree, this will fall back to the older file but the startup output will show this output while it checks for the updated device tree.

For users with unmodified kernels these can be updated to include the new WIFI support with a tar:

This can be installed directly to the board: 

wget https://files.embeddedarm.com/ts-socket-macrocontrollers/ts-4900-linux/kernel/linux-4.9.11-20200701.tar.bz2
tar -xf linux-4.9.11-20200701.tar.bz2 -C /

This can also be used to install over an existing image: 

mkdir /tmp/image/
sudo tar --numeric-owner -xf old-image.tar.bz2 -C /tmp/image/
sudo tar -xf linux-4.9.11-20200701.tar.bz2 -C /tmp/image/
sudo tar --numeric-owner -cjf new-image.tar.bz2 -C /tmp/image .

For users with custom kernels these should be updated to our latest commits:
