LAUNCHXL-F280049C: EEPROM emulation with Flash

user4957458

Part Number: LAUNCHXL-F280049C
Other Parts Discussed in Thread: C2000WARE

Dear

There is already support for F28004X of the EEPROM Emulation?

Similar to (for F2806x)

Luis,

Sorry, we don't have EEPROM emulation support available for F280049.

Please refer to this thread: https://e2e.ti.com/support/microcontrollers/c2000/f/171/t/591767?CCS-TMS320F28377D-How-to-read-and-write-data-to-the-MCU-internal-Flash

Thanks and regards,

Please, provide the C specific instructions (macros and examples) for:
1st Instruction for erase one FLASH sector
2nd Instruction for Write to FLASH
3rd Instruction to Read FLASH

Does this FLASH needs calib()? Is it calib() the same as for 28069M FLASH?

Thanks

Luis Gonçalves

Luis,

Instructions that you requested are available in the Flash API usage example provided in C2000Ware at C:\ti\c2000\C2000Ware_1_xx_xx_xx\driverlib\f28004x\examples\flash\flashapi_ex1_program_autoecc.c

F28004x Flash API (V1.56.01) reference guide link: www.ti.com/.../spnu628
Flash API and ECC wiki link: processors.wiki.ti.com/.../C2000_Flash_FAQ

Note that Flash reads are like RAM reads - nothing different. However, Flash should be initialized for proper wait-states.
Please check "5.9.4 Flash Parameters" in datasheet at www.ti.com/.../tms320f280048.pdf .
You can use Flash_setWaitstates() from driverlib to configure the wait states.

Regarding Flash calibration, please check Flash_initModule() from driverlib.
Flash module used in F28069M is different than that of F28004x. Please read 3.12 Flash and OTP Memory chapter from TRM at www.ti.com/.../sprui33a.pdf.

Please let me know if you have any questions.

Thanks and regards,
Vamsi
