Hi Radxa Team,
do you plan to publish an overlay to use a Waveshare 3.5inch SPI DIplay with the 5B and 5B+ ?
Or does anybody has a solution?
Many thanks
Henrik

here’s a waveshare 3.5 inch common dtsi: https://github.com/radxa-pkg/radxa-overlays/blob/main/arch/arm64/boot/dts/rockchip/overlays/waveshare35-lcd.dtsi
and here’s a example: https://github.com/radxa-pkg/radxa-overlays/blob/main/arch/arm64/boot/dts/rockchip/overlays/rk3588-spi4-m2-cs0-waveshare35.dts
you just need to modify the spi bus and a couple of GPIOs.
sorry, this might be beyond my skills. do you or someone else has an allready working solution?
ok, I’ll make a dts for you when I have time.
Many, many thanks!

ROCK 5B/5B+ may not fit Waveshare 3.5 inch SPI LCD perfectly, because PIN_22 pin is used as SARADC_IN4 instead of GPIO, you may need to use DuPont cable to connect ROCK 5B/5B+ with Waveshare 3.5 inch SPI LCD.
