Other Parts Discussed in Thread: AM5718
While bootiing the custom board made out of AM5718 , SDIO controller is failing. While debugging found the following
[ 0.439445] SCSI subsystem initialized
[ 0.440318] i2c...4
[ 0.440639] palmas 0-0058: Irq flag is 0x00000004
[ 0.470590] palmas 0-0058: POLARITY_CTRL update failed: -121
[ 0.470973] palmas: probe of 0-0058 failed with error -121
On getting closer to the issue found the i2c device read fails . Ie regmap read or write fails. How to debug this further?
