TMS570LS0432: HalCoGen FEE Issue

Part Number: TMS570LS0432
Other Parts Discussed in Thread: TMS570LS1227

Customer reporting the following issue with TI FEE (emulated EEPROM).

 

They have seen this on the following processors:

TMS570LS0432

TMS570LS1227

 

They have a bootloader that is configured to copy unknown FEE blocks.

#define TI_FEE_NUMBER_OF_UNCONFIGUREDBLOCKSTOCOPY    255U

 

The bootloader reads and writes block 1 only.

They have a demonstration application that reads and writes blocks 1 and 2 and possibly others.

 

The expected behavior when writing to a previously erased virtual sector is:

    • Old blocks get copied to the new virtual sector.
    • The old virtual sector is erased.

 

This appears to not work.

When the bootloader writes block 1 to a new virtual sector the old block 2 is lost.

The problem is highly predictable and repeatable.

Is this a known issue?

    Hi Lawrence,

    Before answering I would like to know the details of the FEE Version customer is using.

    Do you know if Following MACRO is used STD_OFF or STD_ON??

    #define TI_FEE_USEPARTIALERASEDSECTOR                       STD_OFF

    I can work with you directly to support this. Lets take this offline and once we have the root cause we can update this thread to close.
