Subject: [PATCH] overlays: seeed-can-fd-hat: clarify how to identify
|
|
HAT version
|
|
|
|
It turns out the used CAN SPI chip is not a good way to identify the version of
|
|
the CAN HAT.
|
|
|
|
There are two different board layouts of the Seeed Studio CAN BUS FD HAT. The
|
|
v1 board doesn't have a battery holder, while the v2 board has. Update the
|
|
overlay README accordinly.
