Hi Hercules champions,

I debug FEE read and write example code in HALCoGen file on TMS570LS0714, i have a question that：

Does this expample code have over time protection? 

I had found that there was a Macro define: 

#define TI_FEE_MAXIMUM_BLOCKING_TIME      600U

in ti_fee_cfg.h, does it means the over time protection time is 600 system clock? 

Thanks!

    Martin,

    The current FEE user guide says:

    4.13 Known Issues / Not supported features

    - Non Polling mode not supported.

    - Immediate block writing not accepted when FEE is performing copy of blocks /

    erase of sectors.

    - No Jobs accepted during copy of blocks /erase of sectors ongoing. (The write job

    which triggered the copy operation will be pending until copy of blocks and erase

    of sectors is completed.)

    - Maximum Blocking time not supported.


    I generated the FEE code for the 714 and while you can see the definition with a value of 600,

    searching the rest of the code shows the definition is never used.   not sure what the feature is supposed to be but anyway for now it seems it is unimplemented.


    Best Regards,
    Anthony
