[DM388] Sensor AR0521 is unstable.

 I have a similar issue like this link :

https://e2e.ti.com/support/processors/f/791/t/600404?-DM388-AR0521-sensor-integration-issue

Same  situation.

I use AR0330 as template to modify it.

Of course I open MIPI mode. But AR0521 sometimes work , sometimes not.

I have another board with chip AM5718

AR0521 + chip AM5718 is perfectly work.

Same AR0521 parameter is in dm388 platform too.

If AR0521 video failed , source code crash at these function:

1.

\ti_tools\iss_03_80_00_00\packages\ti\psp\iss\core\src\iss_comp.c

ISP_RETURN issDrvRawToYuvConfig(iss_config_params_t * config_params,

                                iss_drv_config_t * iss_drv_config)

csi2_wait_phy_reset(); // code stuck here random.

2.

\ipnc_rdk\ipnc_mcfw\mcfw\src_bios6\links_m3vpss\system\system_dctrl_common.c

Int32 System_dispCheckStopList()

status = *(volatile UInt32 *)VPDMA_LIST_STAT_SYNC & 0x00FF0000; // code stuck here random.

3.

Sometime power on OK. But no video output on the screen.

And I set AR0521 stream off/on after power on. Video  output randomly.

Any idea ??????
