I'm trying to use the RELAY2 Click with ci40. It's connected to Mikrobus 1. From the Click schematics we can see that the red led is controlled by PWM pin (SoC PDM_0) and the yellow led is controlled by CS pin (SPI_M0_CS2).
When running relay2 example the red led changes but the yellow stays on. Jumpers don't make any difference, and measured voltage through Primary Expansion Header stays at 3V3. This situation happens with the both Mikrobus ports, so good chances are that the CI40 board is not broken. Click seems to be OK aswell, because the relay switches to the ON state during the boot process.
Has this happened to anyone else, or maybe is there a known way to fix this?
