MIPI CSI2 FIFO overflow error, SBA82308E

We manufacture devices in which we use the Nitrogen8MP module with the i.MX8M Plus processor. One of the MIPI CSI2 inputs has a signal from the TC358743 circuit with a resolution of 1080p60. On the second input, we have a Basler daA3840 camera. The video stream from the camera is routed through an ISP. In the channel with TC358743, the ISP is turned off, and we use ISI instead. Everything worked without any issues with modules featuring a processor marked MIMX8ML8DVNLZAB, 1P33A, SBA62145C. For the next batch, we purchased modules with processors labeled SBA82308E in the third row and started experiencing FIFO overflow errors in the channel with TC358743 (from imx8-mipi-csi2-sam.c). What does the third row in the processor designation mean? Could it be directly related? So far, I have tested 4 units with this designation, and all have the same problem.

Edit. 23.4.2024: It's SBAB2308E and SBAG2145C. Too small letters.

Hello,

You must check the driver. current driver do not support the SBA8230E.
