In beagleplay beagleconnect setup, the AP is not directly connected to greybus nodes. The SVC and APBridge tasks are moved to cc1352 coprocessor. This means that there is a need to send cport information between linux host and cc1352. In the initial version of the driver (and the reference implementation gbridge I was using), the greybus header pad bytes were being used. However, this was a violation of greybus spec. The following patchset creates a wrapper around greybus message to send the cport information without using the pad bytes. --- V3: - Rebase on char-misc-next V2: https://lists.linaro.org/archives/list/greybus-dev@xxxxxxxxxxxxxxxx/thread/7YX5I6ZYZTNTAHBH3M3KAMOWXMTAWQNW/ - Add more comments explaining the new greybus hdlc frame payload - Remove msg len warnings. These checks are also performed by `greybus_data_rcvd` and thus no need for it here.
