TMS320F280039: Parameters for Fapi_issueBankEraseCommand()

Linda Zhang84708

Part Number: TMS320F280039
Other Parts Discussed in Thread: C2000WARE

Hello Champs,

As described in F28003x Flash API user guide page 11:

In "flashapi_ex1_programming" project of F28003x examples in C2000ware, there is below operation in "Example_EraseBanks()" function:

u32CurrentAddress = Bzero_Sector8_start;
oReturnCheck = Fapi_issueBankEraseCommand((uint32 *)u32CurrentAddress, 0x001F);

Does above operation mean: erase starting address is 0x88000, the mask sectors are sector 8,9,10,11,12?

Would you please help clarify? Thanks!

Best Regards,

Linda

Hi Linda,

Start address can be any address in the bank.

Sector 5 and above are not protected given the mask above.

Thanks and regars,

Hello Vamsi,

Thank you for your reply. That is to say, after running below operation:

u32CurrentAddress = Bzero_Sector8_start;
oReturnCheck = Fapi_issueBankEraseCommand((uint32 *)u32CurrentAddress, 0x001F);

The result is: The erasing is starting from Sector 8 and sector 8 to 15 and sector 5 to 7 are all erased while sector 0 to 4 are not erased.

Is it correct?

Thanks!

Best Regards,

Linda

Linda,

Irrespective of which address you give with in a flash bank for the first parameter, the second parameter always reflects bit 0 for sector 0 and bit 15 for sector 15.

Hence, above command will erase sectors 5 and above in Bank zero.

Thanks and regards,
Vamsi
