The sample does not work with version FSP version 3.5, E2 Studio 2025.04.1
It outputs a colorful strip.
(Not sure where to start debugging)

Hi @RobertCaoAtBayer ,

When you upgrade version FSP from v3.4.0 to v3.5.0, there are some changes to the Pin Configurations:

The sample is missing some Pin Configurations in FSP version 3.4.0, which is why the sample does not work with FSP version 3.5.0

You can workaround this issue by enabling the following Pin configurations:

• External Memory Interface: SD

• External Memory Interface: SPIBSC

• peripheral:RIIC

Thanks @sangtranjc, your woraround works for me too! I could only guess how it works, though 😆. I have created a branch for this workaround: https://github.com/lvgl/lv_port_renesas-ek-rz_a3m/tree/fsp-v3.5.0. I don't think we will maintain it as there are a lot of FSPs to track if we started maintaining every FSP.

At the time I did not know FSPs could not be upgraded easily so I have updated the README in master to instruct users to download specifically v3.4.0. eb67c23
