Part Number: TMS320F28388D
Other Parts Discussed in Thread: C2000WARE

Tool/software:

Hello,

I am investigating LFU for TMS320F28388D and

I would like to know if you have a reference document and examples for this chip ?
I have read documentation for F28004x but it seems that the implementation must be different as I have a single Flash bank per core available.
Where could I found example of single bank flash partitioning for FW update and rollback possibilities ?
Can this solution be implemented with core 1 and core 2 updates ?

Thank you for your help.

Vic,

- No, we don't have an LFU ref. document for F2838d

- That's correct. F28004x has 2 banks, F28003x has up to 3 banks, whereas F2838x has only 1 bank per core.

- We have a sample implementation in F28002x (1 bank)

C2000Ware_5_02_00_00\driverlib\f28002x\examples\flash

lfu_singlebank is a simple LED blinky App example, flash_kernel_ex3_ldfu is the flash kernel/bootloader.

In this example, we overwrite the complete application in Flash during LFU. To keep the application running, therefore, we copy the necessary ISR to RAM. We also copy over Flash APIs and specific functions from the kernel/bootloader from Flash to RAM. This is because the Flash bank is not RWW (Read While Write).

- Yes, you can have the same approach apply to both CPU1 and CPU2.

Thanks,

Sira

Hello Sira, Thank you for your reply.

From my understanding, examples from C2000Ware_5_02_00_00\driverlib\f28002x\examples\flash overwrite the full image during the update process. Thus, it is not possible to rollback to the previous FW version in case of any error during the process.

Do you have a linker command file example than can help me to split the unique flash bank in two partitions ?
I guess this is the way I should do to have the rollback possibility.
If I want to implement the FW update of CPU1 and CPU2, could I use the Serial Flash Programming method described in SPRABV4H ?
Is the only pre-requesite to have a communication interface (parallele IO, SCI or CAN) AND a GPIO boot mode selection available ?
I am still considering this solution over LFU without knowing which one is the best and most efficient for my case.

Vic,

I don't have a linker cmd file handy for this exact use-case, but it should be easy to create it. You would have 3 separate linker cmd files

- one for the flash kernel/bootloader

- one for the new application

- one for the existing (rollback) application

sprabv4 describes a generic firmware update method that is non LFU based.

It depends on what your specific application needs. Do you need the application to be running during the update or not - this is the key question.

Thanks,

Sira

Sira,

Can you confirm that my understanding is correct ?

In my scenario where I have my flash memory splitted in 3 regions for rollback purpose : [KERNEL] [PART_A] [PART_B]

I should have 1 build configuration that generates the [KERNEL] and flash it 1 time at factory time.

Along the life cycle of the product, I should have 2 other build configurations with associated linker file that generate [PART_A] or [PART_B] images. This way I can send them alternatively to perform the consecutive updates ?

Dear Sira,

I have tried to implement a custom SCI flash kernel getting inspired from f28002/4x examples but I encounter a problem.

While trying to transfer a FW image with the Serial Flash Programmer, the code execution jumps into fmstatFail function (see picture bellow).

This happens just after the sections erasing and before rewriting new data in the flash. I try to have a better understanding by adding the flash_status and status values in the fmstatFail function. Their respective values are 4112 and Fapi_Status_FsmReady so not really helping me.

I have modified the flash kernel so the erase function does not erase the full flash but only a subpart equivalent to my FW image maximum size.

I have checked that ldfuCopyData and ldfuLoad are run from RAM.

I also checked that the typical erasing flow represented in SPNU632 4.2 is respected and it looks to be the case.

Do you have any clue of what could be the reason of this error ?

Vic,

I do see that ldfuCopyData and ldfuLoad are running from RAM addresses.

Did you also ensure that the Flash API library is copied to RAM?

Thanks,

Sira

Hi Sira,
Thank you for your advice.

I have found :

a clock initialization error and also that
the FlashAPI is actually not running from RAM (see picture bellow).

For 1., I suggest that this change could be applied to C2000 examples to avoid encountering wrong hardcoded frequencies :

For 2., I still struggle to have the FlashAPI running from RAM, probably because of a linking issue.

I added the following lines in my linker file,

  GROUP
   {
       .TI.ramfunc
       {
          -l F2838x_C28x_FlashAPI.lib
       }
   }  LOAD = STATIC_CODE,
	  RUN = RAMLS0 | RAMLS1 | RAMLS2 |RAMLS3,
	  LOAD_START(RamfuncsLoadStart),
	  LOAD_SIZE(RamfuncsLoadSize),
	  LOAD_END(RamfuncsLoadEnd),
	  RUN_START(RamfuncsRunStart),
	  RUN_SIZE(RamfuncsRunSize),
	  RUN_END(RamfuncsRunEnd),
	  ALIGN(8)

but -l F2838x_C28x_FlashAPI.lib generates the following warning : ../linker_FLASH_custom_STATIC.cmd", line 147: warning #10068-D: no matching section

The rest of the code using #pragma CODE_SECTION(foo, ".TI.ramfunc") seems to be flashed at the correct place.

Does this warning means that the linker cannot find the library so cannot be put it in the correct address ?

Thank you for your help.

I solved the FlashAPI linking problem by removing the local copy of the F2838x_C28x_FlashAPI.lib in my project and adding a link instead.

However, after fixing this issue I just realized that something is still wrong in the Flash writing process.

At the end of the FW transfer in ldfu_load(), the function call to write the KEY and REV values returns Success but actually fails. When I look at the memory browser, I can see the START value, but can't see nor the REV nor the KEY.

In the memory browser bellow, I am expecting 0x5A5A5A5A 0xFFFFFFFE 0x5B5B5B5B. I can't explain this result.

TI__Mastermind 22870 points

Vic,

The method you've used to copy the Flash API lib from Flash to RAM looks correct (in the linker cmd file), but just to be sure did you look at the .map file and check whether the Flash APIs were mapped to RAM addresses?

Can you try putting a breakpoint before the KEY and REV are written and check whether the intended write values are correct?

Thanks,

Sira

Sira,

The FlashAPI is now running from RAM since I replaced the local copy of F2838x_C28x_FlashAPI.lib by a link.

Regarding the KEY and REV writing issue, it looks like it is related with memory block size and/or ECC.

When I write START at 0x80120 and KEY at 0x80124, it does not work and Fapi_getFsmStatus() returns 0x30.
BUT
when I write START at 0x80120 and KEY at 0x8012C, it works !

In the example flash_kernel_ex3_sci_flash_kernel for F28002x, they do write START, KEY and REV in continuous memory addresses. It is not supposed to work the same way with F2838x ?

Hi Sira,

I think I solved the problem by reshuffling my memory sectors definitions. I was probably trying to write 2 times the same 64 bits block per Flash erase cycle.

So I succeedded to flash the kernel and transmit the Image 1 using the kernel. However, when I try to branch to the LiveDFU fonction stored in the kernel from the Image 1 execution, an Interrupt_illegalOperationHandler() is triggered.

After autobaudlock is performed, I jump to the LiveDFU function stored at the adress 0x80100. To do so I use the method used in flashapi_ex3_live_firmware_update for F28004x.

Unfortunately, it is the first time I encounter this Interrupt_illegalOperationHandler and I don't know what is the reason.

I have checked that the LiveDFU function is at the expected position in memory and this is the case.

Do you have any clue of the reason ?

Could it be that the instruction at address 0x080100 is seen as an invalid instruction despite the fact that the function LiveDFU() is running as expected when run from Kernel Image ?

EDIT :

Even if the call stack shows SysCtl_delay at adress 0x08010E, this is wrong. This function is not located at this address.
I try another location than 0x080100 without success.

UPDATE:

By looking at the disassembly code, I can see that the execution jumps to the correct address and starts executing the LiveDFU() function.
However, when jumping into LdfuLoad() memory sector, there is no instruction to execute.

In my opinion, this is normal as the LdfuLoad() function is not compiled in the active image but is only compiled by the static code.

So even if the ".TI.ramfunc" code section is correctly copied from FLASH to RAM using this line :

How can we expect the RAM to contain the instruction of the ldfuLoad() or ldfuCopyData() ?

I think something is missing in the active image to copy the ldfu functions from the static flash to the correct RAM address.

Thanks again for your help.

Hi Vic,

Are you able to share your .map file for the project to see where the LdfuLoad function is placed in memory?

Thanks and regards,

Charles

Hi Charles,

Thank you for jumping in.
Please see bellow the .map files.

First one is for my static code (flash once).

Based on this observation, I understand why it is not working but I don't know a clean way to fix it. The Ldfuload function is present in Flash from the flashing of the static code so Partition 1 should probably copy it to RAM before using it.

Vic,

Sorry that you are still facing issues. Please give me today to analyze this and see if I can figure out what may be happening here.

I will reply by tomorrow.

Thanks,

Sira

Hi Vic,

So where exactly do we stand today:

You are able to Flash the kernel into the device Flash?

You are able to use the above kernel to Flash Image1 into the device Flash (with START, KEY etc. properly written)?

Using this setup, you send an LFU request from an external host, and execution branches from Image1 to the kernel and then it runs off into the weeds somewhere?

Looking at your .map files, I see the same RAMGS10_13 regions are being used in both the kernel and Image1. Your RamfuncsRunStart is the same address (0x17000) for both the static kernel as well as Image1. This means whatever code you want to copy from Flash to RAM will get copied (first for the kernel), and then get overwritten (when you do the same Flash to RAM copy for Image1).

This should be avoided. Please allocate different Flash and RAM regions for Kernel, Image1, Image2.

"Based on this observation, I understand why it is not working but I don't know a clean way to fix it. The Ldfuload function is present in Flash from the flashing of the static code so Partition 1 should probably copy it to RAM before using it."

This is not necessary. As I mention above, whatever needs to run from RAM in the static kernel (e.g. Flash API lib, specific kernel functions) should be copied from Flash to RAM using a memcpy in the static kernel code, and that will suffice.

Then, whatever needs to run from RAM in Image1 (e.g. specific ISRs that you want running during the LFU) should be copied from Flash to RAM using a memcpy in Image1, and that will suffice.

Likewise, you will do the same in Image2 (so it can work in ping-pong fashion as you go through multiple LFUs).

Please note: I will be out of office all of next week, but I am hoping my responses above will unblock you and help you make progress.

Thanks,

Sira
