TMS570LS1114: FeeManager Driver: Error during CRC calculation

Alex Tchado

Part Number: TMS570LS1114
Other Parts Discussed in Thread: HALCOGEN

Hallo,

In ti_fee_util.c we suspect that the function TI_FeeInternal_FeeManager() does the CRC calculation with wrong parameters.

in line 2258 , we are expecting the call:

TI_FeeInternal_Fletcher16(u8WriteDataptrTemp + TI_FEE_BLOCK_OVERHEAD, u16BlockSize);

instead of:

TI_FeeInternal_Fletcher16(u8WriteDataptrTemp, u16BlockSize);

Can someone please confirm (or infirm) this as failure ? We are using HalCoGen 04.07.00

Thanks and Regards,

Alex

Hi Prathap,

Thanks you very much for your reply. Where can we find validation report (and verification of each bugfix) for each version ?

The only thing we find is this old draft version:

processors.wiki.ti.com/.../TI_FEE_Driver_Validation_Report.pdf

Hi Alex,

We do not deliver validation report anymore.

We have clubbed them in to "Compliance Support package" http://www.ti.com/tool/SAFETI-HALCOGEN-CSP. Note : this is a paid package.

This CRC bug is due to the test gap in the automated flow, tests were added to cover this scenario.
