S32K144: FlexIO Master Receive Blocked for more than 13 bytes

[sundaram_v]

Hello Team,

Currently, we have two S32K144 devices, and one is acting as an IIC master and the other as a slave.

We were implementing the FLEXIO mechanism (Master and Slave) for communication between two S32K144 devices using FREERTOS. We were using the RTM 3.0.0 SDK.

Our communication protocol follows: for each master request, the slave should respond with 15 bytes.

But we understood that FLEXIO Master Receive will support only up to 13 bytes; if it is more than 13 bytes, it is getting asserted.

Could you please help with some suggestions on this? This is very important for us.

Thanks
Sundar

Hi Sundar,

Please update the S32K1 SDK to RTM 3.0.3 or higher. It was fixed in RTM3.0.3, read S32SDK_for_S32K1xx_RTM_3.0.3_ReleaseNotes.pdf 

Best Regards,
Robin
