TMS570LS3137: Having trouble running FAPI F21 libraries to program flash during bootloader

Part Number: TMS570LS3137

Help,

When trying to use the following api calls within the bootloader uart sample code

Fapi_BlockErase

Fapi_initializeFlashBanks

Fapi_setActiveFlashBank

Fapi_enableMainBankSectors

Fapi_issueAsyncCommandWithAddress

I can single step over the functions, but, when I run over the functions, I end up caught in undef_entry or prefetch_entry.

We are calling Fapi_initializeAPI((Fapi_FmcRegistersType *)F021_CPU0_REGISTER_ADDRESS, (uint32_t)SYS_CLK_FREQ); where SYS_CLK_FREQ == 160 and F021_CPU0_REGISTER_ADDRESS == FFF87000

We are running the F21 and bl_flash from RAM. Any help would be appreciated.

Thanks,

Ron

By the way, when I switch to using Bank1, all is well and I can program the flash.

Hi Ron,

You need to execute all flash API related code and data from SRAM, or another flash bank.

Thank you sir,
we are running from RAM and still no luck. Can we use the debugger while working with the flash API?

I was able to get the FAPI library to run from SRAM, but could not get the runtime support library to run from RAM along with our application.

I do have 2 interrupts, rti Compare0 and SCI Rx/Tx. We did try disabling interrupts before calling into the bl_flash functions.

Any suggestions would be helpful,
Ron

Hi Ron,

Have you solved your flash programming issue in your bootloader? I apologize for my late response.

Hello Ron,

In bl_link.cmd, please add section bl_flash.obj (.const) into the flashAPI section. The flash_sector[] data table (constant data) is used by bl_flash.c. The execution might hang in bl_flash.c on the following line unless the .const section is also located in RAM :

while(FAPI_GET_FSM_STATUS != Fapi_Status_Success);

If bl_ymodem.c calls memcpy, it is better to place memcpy to RAM too.
