Subject: Re: [RESEND PATCH v5 0/4] Add Synopsys DesignWare HDMI RX Controller
Hi Shreeya,
I applied your patch to rockchip/next on an FriendlyElec CM3588 device
with arm-trusted-firmware 2.12. This is the same hardware/cable/sources
I used previously
Sadly I could not get it to work at all.
After connection to a HDMI source I get the following error with all
devices and resolutions I tested
# dmesg
snps_hdmirx fdee0000.hdmi_receiver: hdmirx_controller_init wait timer
base lock failed
snps_hdmirx fdee0000.hdmi_receiver: hdmirx_phy_register_write wait cr
write done failed (repeating multiple times)
# v4l2-ctl --list-devices
[...]
snps_hdmirx (platform:fdee0000.hdmi_receiver):
/dev/video2
With the source set to 1920x1080, 60hz RGB I get the following output,
it freezes and creates no file. Notice the wrong resolution
# v4l2-ctl --verbose -d /dev/video2
