AM2432: Uart Polling Bug

Kevin Peng

Part Number: AM2432

Tool/software:

Hi TI Experts,

Customer finds a bug in SDK9.2 in Uart Polling section.

As you could see from the function UART_fifoRead below, the while loop condition is using readSizeRemaining, however, only the tempReadSizeRemaining is getting less in each cycle. This means that tempReadSizeRemaining will be very likely overflow in this while loop, we think we need use tempReadSizeRemaining in the while loop condition, not the readSizeRemaining.

Could you help double check this problem and fix it in the next SDK release please?

Thanks,

Kevin

Hi Prashant,

Thanks for the reply, may I know the "the next SDK release" refers to SDK10.0 onwards or SDK10.1 onwards?

Thanks,

Kevin

Hi Prashant,

Customer feedback that the latest INDUSTRIAL COMMUNICATIONS SDK version is SDK9.2 and published in Mar Y25, and it still does not have the above fix. We know that for MCU SDK10.1 onwards will have this change, but customer still needs using INDUSTRIAL COMMUNICATIONS SDK, customer wants to know when the next INDUSTRIAL COMMUNICATIONS SDK will release, and will it also have this fix?

Thanks,

Kevin

Hi Kevin,

I have asked this internally and will let you know.

So INDUS COMMS SDK is tested with a specific version/package of MCU PLUS SDK.

I am sure the next release would incorporate the changes, but allow me sometime to comment on this.

Regards,

Vaibhav
