Hi Amit,

I'm seeing quite a strange behavior of RedPine module.
It connects perfectly fine to one of access points but fails
to connect to another.

Moreover after that failure RSI driver starts to flood me with
messages saying:
--------------------->8--------------------
rsi_91x: rsi_sdio_check_buffer_status: Failed to read status register
--------------------->8--------------------

Below you may find details of my 2 experiments.
Note I use vanilla Linux kernel v4.14.4

Any ideas what could be wrong?

Could you enable driver debug zones and share dmesg log for analysis?

echo 0xffffffff > /sys/kernel/debug/phy0/debug_zone
