what BUILD for a correct "grove cape" support ?

which release do I have to download for a BBGW with the seedstudio grove cape fully accessible ?

https://rcn-ee.online/rootfs/bb.org/testing/

If I run mraa-gpio to have the list of GPIO configured in the system on a RCN Linux I have as result a list that is not the same as in the official debian image.

And of course, GPIO ports on the CAPE are not working …

Did i something wrong ?
