Unresolved symbol: “Fapi_enableEepromBankSectors” when using F021 Flash API.

Jerome Beauvais

Hello

I need to program the EEPROM in the following configuration: RM48 microcontroller with CCS Version 6.1.0
To install the F021 Flash API I downloaded the file spnc033.zip then I executed the file F021FlashApi-02.01.01-windows-installer.exe.
The include files have been installed in the directory: "C:\ti\Hercules\F021 Flash API\02.01.01\include\”
The lib files have been installed in the directory: “C:\ti\Hercules\F021 Flash API\02.01.01\”
I indicated those directories in CCS project properties.
Then I wrote the following instructions in the project:

Fapi_StatusType Fapi_enableEepromBankSectors(uint32_t u32SectorsEnables_31_0, uint32_t u32SectorsEnables_63_32);

Fapi_StatusType FapiResult;

uint32_t EEPROM_SectA = 1<<0;

uint32_t EEPROM_SectB = 0;

…

FapiResult = Fapi_enableEepromBankSectors(EEPROM_SectA, EEPROM_SectB);

Then I got the following error: Unresolved symbol: “Fapi_enableEepromBankSectors”.
What is missing?
Thanks for your Help.

Hi Jerome,

Can you check if you have the F021 library included in the file search path during Link command like below? Please give a try. Below example is linking to a big endian library. In your case for RM48 you will need to link the F021_API_CortexR4_LE_V3D16.lib instead. Or you can just copy the F021_API_CortexR4_LE_V3D16.lib to your project source folder. Please give a try.

Hi Charles,

I tried the following configuration and it's OK.

Thanks for your help.

Hi Charles
I got another error when I declared the function: Fapi_StatusType Fapi_issueProgrammingCommand(uint32_t *pu32StartAddress, uint8_t *pu8DataBuffer, uint8_t u8DataBufferSizeInBytes, uint8_t *pu8EccBuffer, uint8_t u8EccBufferSizeInBytes, Fapi_FlashProgrammingCommandType oMode);
The error is:
"Fapi_FlashProgrammingCommandType" is undefined main.c
Thanks for your help
Kind regards

Hi Jerome,
Do you have the #include "F021.h" in the main.c?

Hi Jerome,

I don't know why you are having the compile problem. Here I created a simple project for RM48 device that erases and programs some data to the EEprom bank. You should see the image below with the EEprom bank programmed with data after you run it.

Hi Charles and thanks you very much for your example.
Something is very strange, when I tried to launch it in debug mode I got the following error:

It looks like it interferes with an old project which is not present at that time.
If I copy your code (the main loop) in my project It’s working very well.
So I can now continue my development.
I have another question, when I launch again a debug session, CCS erases the bank 7 = EEPROM and I do not want that. Is it possible to disable this action?
Thanks very much for all.
Kind regards
Jerome

Hi Jerome,

Are you asking if you already have data in bank7 and you don't want the CCS to erase it the next time you are loading a new program to the flash bank0? If this is the case, you can go to Tools->On-Chip Flash and uncheck all the sectors in Bank7 like below.

Yes Charles It was my question.
Thanks a lot for all
