This series is tested with IMX219 camera sensor.are on 20200616Are you using same device tree as I sent offline? It uses CSI A for IMX219.I now have the imx219 detected, but if I try to stream I get this: $ v4l2-ctl --stream-mmap <[ 512.840944] video4linux video0: MW_ACK_DONE syncpt timeout: -11 [ 512.972975] video4linux video0: frame start syncpt timeout: -11 <VIDIOC_DQBUF: failed: Input/output error [ 513.180770] video4linux video0: MW_ACK_DONE syncpt timeout: -11 And then everything hangs and I need to reset. I'm testing with the media_tree master with your patches on top. Regards, HansDoes you setup also uses CSI-A as x2 for IMX219?I tested them on Jetson Nano + IMX219 rasp PI module and also on JetsonTX1 + IMX274. I did not see any issue and am able to capture from both.Will try again on my side with today's latest linux-next and update result.Please use the media_tree master, that's what I use as well. I did some more testing and there is something weird going on.I have a Leopard Imaging camera expansion board (LI-JTX1-MIPI-ADPT) withthree camera connectors. See here for the datasheet:https://www.leopardimaging.com/uploads/LI-TX1-KIT-IMX274M12-T_datasheet.pdfThe first connector (with an IMX274) causes this error: $ v4l2-ctl -d1 --stream-mmap [ 599.265885] video4linux video1: MW_ACK_DONE syncpt timeout: -11 [ 599.473883] video4linux video1: MW_ACK_DONE syncpt timeout: -11 [ 599.681904] video4linux video1: frame start syncpt timeout: -11 [ 599.681909] video4linux video1: MW_ACK_DONE syncpt timeout: -11 <VIDIOC_DQBUF: failed: Input/output error [ 599.897884] video4linux video1: MW_ACK_DONE syncpt timeout: -11Similar to the test above where I had an IMX219 connected. Except it didn't hang with the IMX274 (I'm beginning to suspect a locking issue in the imx219driver that is causing the hang, I'll look at that tomorrow).If I connect the IMX219 to the middle camera connector, then it works fine. I think I tested this with the IMX274 as well, but I'm not 100% certain, alsosomething to double check tomorrow.If I connect the IMX219 or IMX274 to the third camera connector, then I get this:Would like to know CSI port mapping to connectors as mipi calibrate pads cells need to be updated in device tree based on CSI port in use.Will see if I can find that from DS link you sent above.$ v4l2-ctl -d0 --stream-mmap[ 820.513866] tegra-mc 70019000.memory-controller: viw: write @0x00000001b5fd08c0: EMEM address decode error (EMEM decode error)[ 820.525354] tegra-mc 70019000.memory-controller: viw: write @0x00000001b5fd08c0: EMEM address decode error (EMEM decode error)[ 820.536780] tegra-mc 70019000.memory-controller: viw: write @0x00000001b5fd08c0: EMEM address decode error (EMEM decode error)[ 820.548222] tegra-mc 70019000.memory-controller: viw: write @0x00000001b5fd08c0: EMEM address decode error (EMEM decode error)[ 820.559639] tegra-mc 70019000.memory-controller: viw: write @0x00000001b5fd08c0: EMEM address decode error (EMEM decode error) <[ 820.646931] tegra-mc 70019000.memory-controller: viw: write @0x00000001b5fd08c0: EMEM address decode error (EMEM decode error) [ 820.658355] tegra-mc 70019000.memory-controller: viw: write @0x00000001b5fd08c0: EMEM address decode error (EMEM decode error) [ 820.669797] tegra-mc 70019000.memory-controller: viw: write @0x00000001b5fd08c0: EMEM address decode error (EMEM decode error) [ 820.681216] tegra-mc 70019000.memory-controller: viw: write @0x00000001b5fd08c0: EMEM address decode error (EMEM decode error) [ 820.692601] tegra-mc 70019000.memory-controller: viw: write @0x00000001b5fd08c0: EMEM address decode error (EMEM decode error)<<<<<<<<<<<<<<< 14.50 fps <<<<<<<<<<<<<<< 14.75 fps <<<<<<<<<<<<<<< 14.73 fps <<<<<<<<<<<<<<< 14.80 fps <<<<<<<<<<<<<[ 825.517854] tegra_mc_irq: 133437 callbacks suppressed[ 825.517874] tegra-mc 70019000.memory-controller: viw: write @0x00000001b5fd08c0: EMEM address decode error (EMEM decode error) [ 825.534395] tegra-mc 70019000.memory-controller: viw: write @0x00000001b5fd08c0: EMEM address decode error (EMEM decode error) [ 825.545833] tegra-mc 70019000.memory-controller: viw: write @0x00000001b5fd08c0: EMEM address decode error (EMEM decode error) [ 825.557280] tegra-mc 70019000.memory-controller: viw: write @0x00000001b5fd08c0: EMEM address decode error (EMEM decode error) [ 825.579346] tegra-mc 70019000.memory-controller: viw: write @0x00000001b5fd08c0: EMEM address decode error (EMEM decode error) [ 825.590764] tegra-mc 70019000.memory-controller: viw: write @0x00000001b5fd08c0: EMEM address decode error (EMEM decode error) [ 825.602188] tegra-mc 70019000.memory-controller: viw: write @0x00000001b5fd08c0: EMEM address decode error (EMEM decode error) [ 825.613649] tegra-mc 70019000.memory-controller: viw: write @0x00000001b5fd08c0: EMEM address decode error (EMEM decode error) [ 825.625075] tegra-mc 70019000.memory-controller: viw: write @0x00000001b5fd08c0: EMEM address decode error (EMEM decode error) [ 825.645983] tegra-mc 70019000.memory-controller: viw: write @0x00000001b5fd08c0: EMEM address decode error (EMEM decode error)< 14.64 fps <<<<<<<<<<<<<<<< 14.87 fps <<<<<<<<<<<<<<< 14.89 fps Something is producing EMEM address decode errors. But it is streaming.above memory controller errors may be due to access faults and not sure why these show up on your setup. I never have these with my testing.Also I am using CMA alloc of 256MB and not sure if low CMA alloc size is causing this. Can you try with CMA alloc size of 256MB?If I enable the TPG then everything is fine.So I have currently three different behaviors for three camera connectors.Do you have a datasheet for your Jetson TX1 camera board? It could be usefulto compare the two.Yeah we have and will send it offline.Also based on connector mapping to corresponding CSI port, mipi-calibrate pad cell value also need to be changed.Below is for CSI-A nvidia,mipi-calibrate = <&mipi 0x001>Regards, HansConnector-1 is CSI-AB where you had timeouts. Connector-2 is CSI-CD and this works for you.Connector-3 is CSI-EF and this works for streaming from above but there's memory access fault errors (EMEM address decode errors)These EMEM decode errors are not related to connector but its just they showed up during connector-3 testing I believe. Can you also keep CMA size to 256MB and try?Not sure if CSI-AB issue with FS and MW_ACK sp timeouts are due to some HW/setup issue. Streaming should work on CSI-AB ports as well just like CSI-CD/EF with proper device tree change for port index and mipi calibrate cells for corresponding ports.On my setup that I tested IMX274 is on CSI-AB. Will update my side test results with today's linux-next
Hans,We have this module as well. Will try to get this today for testing and will update just to make sure of this combo as well on my side.
