opi-5-plus-user Posted 2 hours ago Posted 2 hours ago I have tried to get the CSI port working on my Radxa Zero 3W with the GEEKOM X1301 HAT, and now I can get the chip to show up in /dev, however there seems to be an issue when I try to access it, as I keep getting ioctl errors. I started by copying over the .dtbo files from the regular radxa official image, and putting them into the overlay-user folder in /boot. Then I enabled the radxa-zero3-tc358743.dtbo overlay, which gets the devices to show up. I am following this guide from GEEKOM https://wiki.geekworm.com/X1300_Software, however, I keep getting ioctl errors when trying to set the EDID file on the Radxa Zero. On the Raspberry Pi, this was not an issue. Here is the output of my media-ctl: media-ctl -d /dev/media0 -p Media controller API version 6.1.115 Media device information ------------------------ driver rkisp-vir0 model rkisp0 serial bus info platform:rkisp-vir0 hw revision 0x0 driver version 6.1.115 Device topology - entity 1: rkisp-isp-subdev (4 pads, 8 links, 0 routes) type V4L2 subdev subtype Unknown flags 0 device node name /dev/v4l-subdev0 pad0: SINK,MUST_CONNECT [stream:0 fmt:UYVY8_2X8/640x480 field:none colorspace:srgb crop.bounds:(0,0)/640x480 crop:(0,0)/640x480] <- "rkisp-csi-subdev":1 [ENABLED] <- "rkisp_rawrd0_m":0 [] <- "rkisp_rawrd2_s":0 [] pad1: SINK <- "rkisp-input-params":0 [ENABLED] pad2: SOURCE [stream:0 fmt:YUYV8_2X8/640x480 field:none colorspace:smpte170m quantization:full-range crop.bounds:(0,0)/640x480 crop:(0,0)/640x480] -> "rkisp_mainpath":0 [ENABLED] -> "rkisp_selfpath":0 [ENABLED] -> "rkisp_iqtool":0 [ENABLED] pad3: SOURCE -> "rkisp-statistics":0 [ENABLED] - entity 6: rkisp-csi-subdev (6 pads, 5 links, 0 routes) type V4L2 subdev subtype Unknown flags 0 device node name /dev/v4l-subdev1 pad0: SINK,MUST_CONNECT [stream:0 fmt:UYVY8_2X8/640x480 field:none colorspace:srgb] <- "rockchip-csi2-dphy0":1 [ENABLED] pad1: SOURCE,MUST_CONNECT [stream:0 fmt:UYVY8_2X8/640x480 field:none colorspace:srgb] -> "rkisp-isp-subdev":0 [ENABLED] pad2: SOURCE -> "rkisp_rawwr0":0 [ENABLED] pad3: SOURCE pad4: SOURCE -> "rkisp_rawwr2":0 [ENABLED] pad5: SOURCE -> "rkisp_rawwr3":0 [ENABLED] - entity 13: rkisp_mainpath (1 pad, 1 link) type Node subtype V4L flags 0 device node name /dev/video0 pad0: SINK <- "rkisp-isp-subdev":2 [ENABLED] - entity 19: rkisp_selfpath (1 pad, 1 link) type Node subtype V4L flags 0 device node name /dev/video1 pad0: SINK <- "rkisp-isp-subdev":2 [ENABLED] - entity 25: rkisp_rawwr0 (1 pad, 1 link) type Node subtype V4L flags 0 device node name /dev/video2 pad0: SINK <- "rkisp-csi-subdev":2 [ENABLED] - entity 31: rkisp_rawwr2 (1 pad, 1 link) type Node subtype V4L flags 0 device node name /dev/video3 pad0: SINK <- "rkisp-csi-subdev":4 [ENABLED] - entity 37: rkisp_rawwr3 (1 pad, 1 link) type Node subtype V4L flags 0 device node name /dev/video4 pad0: SINK <- "rkisp-csi-subdev":5 [ENABLED] - entity 43: rkisp_iqtool (1 pad, 1 link) type Node subtype V4L flags 0 device node name /dev/video5 pad0: SINK <- "rkisp-isp-subdev":2 [ENABLED] - entity 49: rkisp_rawrd0_m (1 pad, 1 link) type Node subtype V4L flags 0 device node name /dev/video6 pad0: SOURCE -> "rkisp-isp-subdev":0 [] - entity 55: rkisp_rawrd2_s (1 pad, 1 link) type Node subtype V4L flags 0 device node name /dev/video7 pad0: SOURCE -> "rkisp-isp-subdev":0 [] - entity 61: rkisp-statistics (1 pad, 1 link) type Node subtype V4L flags 0 device node name /dev/video8 pad0: SINK <- "rkisp-isp-subdev":3 [ENABLED] - entity 67: rkisp-input-params (1 pad, 1 link) type Node subtype V4L flags 0 device node name /dev/video9 pad0: SOURCE -> "rkisp-isp-subdev":1 [ENABLED] - entity 73: rockchip-csi2-dphy0 (2 pads, 2 links, 0 routes) type V4L2 subdev subtype Unknown flags 0 device node name /dev/v4l-subdev2 pad0: SINK,MUST_CONNECT [stream:0 fmt:UYVY8_2X8/640x480@10000/600000 field:none colorspace:srgb] <- "m00_b_tc35874x 2-000f":0 [ENABLED] pad1: SOURCE,MUST_CONNECT -> "rkisp-csi-subdev":0 [ENABLED] - entity 76: m00_b_tc35874x 2-000f (1 pad, 1 link, 0 routes) type V4L2 subdev subtype Sensor flags 0 device node name /dev/v4l-subdev3 pad0: SOURCE [stream:0 fmt:UYVY8_2X8/640x480@10000/600000 field:none colorspace:srgb] [dv.caps:BT.656/1120 min:1x1@0 max:10000x10000@310000000 stds:CEA-861,DMT,CVT,GTF caps:interlaced,progressive,reduced-blanking,custom] [dv.query:no-link] [dv.current:BT.656/1120 640x480p59 (800x525) stds:CEA-861,DMT flags:has-cea861-vic] -> "rockchip-csi2-dphy0":0 [ENABLED] The GEEKOM does seem to require some GPIOs, as shown in the second picture from this link https://geekworm.com/products/x1301, however, these all seem to be for audio functionality, which I have disabled. I currently only have the GEEKOM X1301 connected through the CSI Port to the Radxa Zero, as it physically cannot have the GPIOs and the CSI port connected at the same time.

The HAT's power LED doesn't light up for some reason, and the device also isn't detected when I plug in any other devices HDMI out into the HDMI IN on the HAT. 0 Quote
