Hello, I'm interfacing the F021 library to progam the TMS570LSxxx5 family and I have some questions:
This function returns information about the bank starting address, number of sectors, sector sizes, andbank technology type. The information is returned in a struct Fapi_FlashBankSectorsType. The membersare as follows:• oFlashBankTech – Indicates if bank is an FLEP, FLEE or FLES bank type• u32NumberOfSectors – Indicates the number of sectors in the bank• u32BankStartAddress – Starting address of the bank• au8SectorSizes – An array of sectors sizes for each sector in the bank
a- What mean FLEP, FLEE and FLES?b- au8SectorSizes does not contain the sector size value. For example on Bank0 the first value is au8SectorSizes=16 and the last au8SectorSizes=64 could you explain me why?
The supplied starting address to program at plus the data buffer length cannot exceed the bank data width. (Ex.Programming 14 bytes on a 16 byte wide bank starting at address 0x4 is not allowed.)
a- Where can I found the bank data width information?b- Can I program the same bank two time or I need to perform an erase before?
a) These are the different types of bank technology we have in F021 devices. Currently, all released TMS570LSx1xxx devices have only have FLEP type banks.
b) This is an oversight on my part. I need to include the following table in the API documentation:
a) The bank size information is available in the F021 Flash Module chapter of the device's Technical Reference Manual.
b) You may program a bank multiple times before erasing. If programming the same location more than once before an erase, you can only program bits with a 1 value to 0. If you try to program a 1 into a bit that is 0, the the programming operation will fail.
