Hello,
I’m working on an auvidea J130 + TX2 and I’m testing the kernel https://github.com/InES-HPMM/linux-l4t-4.4 because I need tc358840 driver but I cannot initialize the toshiba chip:
tc358840 2-000f: camera_common_regulator_get vif ERR: fffffffffffffdfb
tc358840 2-000f: cannot get regulator vif -517
tc358840 2-000f: Couldn’t power init
tc358840 2-001f: camera_common_regulator_get vif ERR: fffffffffffffdfb
tc358840 2-001f: cannot get regulator vif -517
tc358840 2-001f: Couldn’t power init
Auvidea is not giving any informations and almost every answer of their support department is useless.
As I can understand the dtsi doesn’t initialize the regulator but the file provided by auvidea and/or by the InES-HPMM tree are the same and are not ok.
Hello , Have you been able to solve the issue ? I have the exact same problem for my custom board . I am not sure how should i change the dts file to get rid of this error .let me know if you have any updates.
Regards
Hello
the driver works as expected using for example the board from www.pender.ch but it doesn’t work with the auvidea J130 because they have not released the DBC/BDS for tc358840
Hi have someone tried to work something out on his own? Since there is no real info on when Auvidea will release this, I have tried to patch this myself, with no success at the moment.
From sources I gathered you have to modify the csi_port in the dts file and maybe (not sure nor which) some gpio pins as they are not the same on the j130. After hundreds of different tests, the reason why the driver can’t load (thus no dev/video* appearing) is mystifying.
