Hi Jerry,
I’m not sure I understand. There was an older L4T release that contained an IMX477 driver that included several modes (including the 4032x3040 mode) which are no longer included in the current L4T release. The only way I can test 4032x3040 is by using the Arducam/RidgeRun patched drivers. What exactly will be changing in future releases regarding the IMX477 driver? IMO, the 4032x3040 mode should be added back into the stock Nvidia driver as it does work perfectly fine with Argus at 30fps. As to why it doesn’t work with V4L2 is still a mystery…
