It adds support for Iris 2.0 SD card, which is something we would like to have, and it says it is available for T20.
However this image is newer than 2.8.7, which is the latest available according to the matrix you sent earlier. Is it possible to installl 5.1.0 on T20?
Although the T20 is listed on this issue and is related to BSP 5.1.0, this issue is specifically about “Support Iris 2.0 SD Card (Without External Pull-Ups)” and does not mean that BSP 5.1.0 supports any of Colibri VF50, Colibri VF61, Colibri T20, Colibri T30.
Those modules were removed from the list and soon it will be updated on the public issue tracker to avoid confusion. Thanks for helping us fix the information.
