Hey. I am trying to write a driver for toshiba tc358748. I took imx219 as a basis. Working with devkit jetson nano A02. I have configured the tc358748 to output 1920 * 1080, 2 data lines, color bars. Came across a problem. loading the driver. dmesg [ 54.648747] tc: loading out-of-tree modul…

hello djager471, please access TX1 TRM from download center, you should check the Chapter-29.16 for MIPI-CSI registers reporting. for example, CSI_CSI_CILA_STATUS_0 = 0x40040, bit-6 & bit-18 indicate there’s lane control errors. are you able to enable test-pattern-generator on the tc358748 chips…

hello djager471, there’s nothing according to your tracing logs, it means VI engine did not receive any active MIPI signaling. you may review your power-on sequence in kernel driver, regulator settings, port bindings , and Debugging Tips . thanks

I did from Imx219. I think that there should be no mistake. tegra210-porg-p3448-common.dtsi removed include “porg-platforms/tegra210-porg-camera-rbpcv2-imx219.dtsi” include “porg-platforms/tegra210-porg-camera-rbpcv2-dual-imx219.dtsi” include “porg-plugin-manager/tegra210-porg-plugin-manager.dt…

Hey. I connected imx219 and saw an image. But my log ‘cat / sys / kernel / debug / tracing / trace’ remains empty. What ideas?

hello djager471, because Nano did not have such log level settings, [image] djager471: root@jetson-desktop:/home/jetson# echo 2 > /sys/kernel/debug/camrtc/log-level bash: /sys/kernel/debug/camrtc/log-level: No such file or directory please have alternative way to enable dynamic debug flag, …

Нow to get debug information when writing your driver?

hello djager471, you may also check imx219 sources, for example, $L4T_Sources/r32.4.3/Linux_for_Tegra/source/public/kernel/nvidia/drivers/media/i2c/imx219.c dynamic_debug flag will enable dev_dbg() functions, to enable that print into kernel messages, i.e.$ dmesg please also refer to Building t…

No matter what I do, I always get the same error. Tell me where to look? Physically I see the signals on the oscilloscope. Tried setting tc358748 to different resolutions. [ 871.813132] video4linux video0: frame start syncpt timeout!0 [ 871.819167] video4linux video0: TEGRA_VI_CSI_ERROR_STATU…

Hey. I figured out the capture problem. There was poor contact in the board. I grab a picture: [webcam] Most of the frames are broken. What could be the problem?

hello djager471, this looks like you’re not assign correct stride alignments, you should note that VI requires atom (64-Byte) aligned. could you please enable preferred_stride controls via v4l2 standard controls for verification, for example, $ v4l2-ctl -d /dev/video0 ... --set-ctrl preferred_st…

Maybe you find here useful info. I got a tc358743xbg I hope some day somebody make a driver for Nano or NX should be great, but I guess it is a hard job
