Boot ROM: Flash API [Flash_Program( ) Function]

Revision(s) Affected

0

Details

The Flash API (V1.00) in the device boot ROM contains a coding error in the Flash_Program( ) function.

Workaround(s)

For the TMS320F28027, TMS320F28023, or TMS320F28021 devices: Follow the instructions in the Flash2802x_API_Readme.pdf file of the Flash API V1.00 release to replace the Flash_Program( ) function in the boot ROM with the version in the Flash API V1.00a software library. Alternatively, use the Flash API V2.00 software library.

For the TMS320F28026 or TMS320F28022 devices: Use the Flash API V2.00 software library.

The Boot ROM in Silicon Revision A will be updated to the Flash API V2.01 to fix this issue. The ROM symbol library will be updated to V2.01, which will be functionally equivalent to the V2.00 software library. Any application which uses the Flash API symbol library V1.00 will need to be rebuilt using the updated symbol library. Any application which uses the V2.00 software library can optionally upgrade to the V2.01 symbol library to conserve RAM memory. This has been fixed in revision A silicon.
