Hi, TI experts,

We want to reset csirx on our tda4ve board by following below steps:

CameraFxns_4_to_1.streamOff(0);
appLogWaitMsecs(1);

/* Stop streams only if this is last active Virtual context */
*((volatile unsigned int *)(0x04504100)) = 0x02;
/* Stop all virtual channel */

/* VC0 */
regval = *((volatile unsigned int *)(0x04500020));
*((volatile unsigned int *)(0x04500020)) = (regval & 0x7FFFFFFF);
/* VC1 */
regval = *((volatile unsigned int *)(0x04500040));
*((volatile unsigned int *)(0x04500040)) = (regval & 0x7FFFFFFF);/* VC2 */
regval = *((volatile unsigned int *)(0x04500060));
*((volatile unsigned int *)(0x04500060)) = (regval & 0x7FFFFFFF);

/* VC3 */
regval = *((volatile unsigned int *)(0x04500080));
*((volatile unsigned int *)(0x04500080)) = (regval & 0x7FFFFFFF);
appLogWaitMsecs(10);

/* assert pixel interface reset */
regval = *((volatile unsigned int *)(0x04500010));
*((volatile unsigned int *)(0x04500010)) = (regval & 0xFFFFFFFE);

/* reset streams before configuration */
*((volatile unsigned int *)(0x04504100)) = 0x10;

regval = *((volatile unsigned int *)(0x04504104));
/* Wait for stream to become IDLE */
while (((regval & (1 << 8))!= 0x0U) && ((regval & (0xF << 4)) != 0x0U))
{
regval = *((volatile unsigned int *)(0x04504104));
}

/* Enable DMA context for PSIL thread */
/* VC0 */
regval = *((volatile unsigned int *)(0x04500020));
*((volatile unsigned int *)(0x04500020)) = (regval | 0x80000000);
/* VC1 */
regval = *((volatile unsigned int *)(0x04500040));
*((volatile unsigned int *)(0x04500040)) = (regval | 0x80000000);
/* VC2 */
regval = *((volatile unsigned int *)(0x04500060));
*((volatile unsigned int *)(0x04500060)) = (regval | 0x80000000);

/* VC3 */
regval = *((volatile unsigned int *)(0x04500080));
*((volatile unsigned int *)(0x04500080)) = (regval | 0x80000000);

/* start streams */
*((volatile unsigned int *)(0x04504100)) = 0x01;
appLogWaitMsecs(10);

CameraFxns_4_to_1.streamOn(0);

buy afther doing above steps, the streams can not be recover.

can you help to find what was wrong?

Hi xie jc,

but why do you want to reset CSIRX? Can you please help me understand the reason for this change?

Regards,

Brijesh

Hi, Brejesh,

Thanks.

Because we have found that sometimes the program gets stuck in csirx, and we have already applied a patch provided by TI (patched at tda4vm sdk 8.4), we want to add a recovery mechanism to see if it can recover when an exception occurs.

Hi Xie JC,

But under what condition it gets stuck? Are you seeing some overflow or some other errors? I did not understand why you require to reset CSIRX.

Hi, Brijesh,

Thanks.

I understand your concern. We encounter issues when powering up and displaying the image. We have confirmed that the deserializer is providing MIPI data to the SoC, but csirx gets stuck. Previously, we applied a patch on the TDA4VM SDK 8.4, but the issue still occasionally occurs. Therefore, we are looking for a recovery mechanism to handle exceptions. As for why we are debugging on VE, it is simply because I think the implementation of this part of the code is similar, so we are testing on VE. Can you please directly tell me which registers need to be operated on to recover csirx from its stuck state?

Hi xie jc,

Any further update on this thread? Lets know if we can close it.
