Store data and variables into flash for f28027F launchpad

Hank,

Please provide some additional details about the problem so that we can better help you.

Thanks,

Ozino

 

Hi Hank,

You should be able to emulate EEPROM on a Flash sector.
Check this link:www.ti.com/.../litabsmultiplefilelist.tsp

Hi Gautam

Is any tool can do the verification of the data we saved into FLASH?

Hank

Hi Gautam
I found there are some flash API under this PATH.
C:\ti\controlSUITE\libs\utilities\flash_api\2802x\v201a\
Is that help the EEPROM emulation?

My platform is LAUNCHXL-F28027F.

Should I use the 2802x\v201a or 2802x\v201 ?

Hank

The above link that I've attached has the EEPROM specific API. There's verification tool as such but you can check using CCS debugging tools.

Hi Gautam

Thanks for the help, I will try the EEPROM later, cause I got the other problem now.

I import this proj and learning.
C:\ti\controlSUITE\libs\utilities\flash_api\2802x\v201a\example_ccsv5

But when I watch the array "Buffer[]" in watch window, it always show 2989.
And I can't stop in the Example_CallFlashAPI, even the break point was set.

I reference this page
processors.wiki.ti.com/.../FAQs

and do the instruction below.
On the "Target" tab uncheck the "Halt at program termination" and "Enable CIO function use".

So, how do I watch the data that written in the FLASH?

And other question, can I change the 4 sector into 6 sector or more?

Hank

Hi Gautam

I can use the Memory Browser and (.cmd) file as your advice now, but I got one question.
Can I use the memory address from 0x3F0000 ~ 0x3F4000?

Hank

Hi Gautam

Thank you for your help, I can run the Flash2802x_API will now.

I found it can use the memory address from 0x3F0000 ~ 0x3F4000.

My next step is Integrate the Flash2802x_API into the FOC project.

C:\ti\motorware\motorware_1_01_00_15\sw\solutions\instaspin_foc\boards\boostxldrv8301_revB\f28x\f2802xF\projects\ccs5\proj_lab05a

It looks like to take me more times.
But I finally got the progress. Thank you again.

Hank

You should be able to. Check the memory table in datasheet.

Hi Gautam

I found the some define in Flash2802x_API_Library.h.

// All sectors on an F2802x - Sectors A - D
#define SECTOR_F2802x (SECTORA|SECTORB|SECTORC|SECTORD)


If I modify the (.cmd) file with this
FLASHB : origin = 0x3F6000, length = 0x0007FF /* on-chip FLASH */
FLASHEE : origin = 0x3F6800, length = 0x007FF /* on-chip FLASH */

Is it possible that just erase the address from 0x3F6800 to 0x3F6FFF ?

Hank

Here's the doc that you can go through for your device:
