We are recently testing the adequation of FPGA based MIPI TX solutions with NVIDIA Jetson boards.
We managed to capture frames (with v4l2 for now) with the Jetson nano, but we had negative results on XavierNX products. In both cases, we use the standard dev kits.
On the XavierNX, the following errors are observed on dmesg:
v4l2-ctl --set-fmt-video=width=1920,height=1080,pixelformat=RG10 --set-ctrl bypass_mode=0 --set-ctrl sensor_mode=2 --stream-mmap --stream-count=1 -d /dev/video0 --stream-to=2MP.raw ... [ 297.116585] [RCE] vi5_hwinit: firmware CL2018101701 protocol version 2.2 [ 297.145314] tegra194-vi5 15c10000.vi: corr_err: discarding frame 1, flags: 32, err_data 512 [ 297.165252] tegra194-vi5 15c10000.vi: corr_err: discarding frame 0, flags: 96, err_data 12584034 [ 297.212101] tegra194-vi5 15c10000.vi: corr_err: discarding frame 0, flags: 32, err_data 1186
When investigating the differences between Nano and XavierNX, we noticed that the voltage level of power down and master clock is not specified on the Nano datasheet: (Nano of the left, XavierNX on the right)
Could you please provide this voltage ?
Also, if anyone has an idea why frames are discarded on the XavierNX …
