hi,
i am using dm8127 processor on my custom camera board with ipnc rdk v 3.8.0, there is 4 i2c instance used on it.
i am able to access all peripherals connected to i2cs and is working fine when camera firmware is not running on system board.
but when i start camera firmware, i lose access of devices connected on i2c bus 2, when i access devices, it shows "i2c 2 controller timed out".
fyi, we are using i2c-2 instance on ball no AE21, AA20 with PINCNTL135,136 respectively.
on my board image sensor is connected on I2C bus 0 and we have modified the hdvpss and iss code, and system is
able to capture image from it. we've disabled some of pin muxing functionality of iss and hdvpss code which was over writing the i2c 2 pin mux.
i am using below source code:
Source/ti_tools/iss_03_80_00_00/packages/ti/psp/platforms/ti814x/src/iss_platformTI814x.c
Source/ti_tools/hdvpss_01_00_01_37/packages/ti/psp/platforms/ti814x/src/vps_platformTI814x.c
but result is still same.
Please let me know what is causing problem here on I2C bus 2.
Awaiting for your prompt response.
regards,
Akash
