MSP430F5342: Field update of MSP430F5342 via UART

Hello William,

Sorry for the delay.  I am looking into this and will provide some feedback shortly.

Hello Eddie,

Any update about a CCS custom BSL for the MSP430 F5342?

Regards,

- William.

Hi William,

Please see the thread below which is similar to your question.  You could start with the MSP430F5438A project and adjust the F5342 CCS linker file to your memory needs.

Hi Eddie,

I appreciate your response.  Unfortunately, adjusting the linker file from the CCS_v7_MSP430F543xA_TA_UART project does not work.  It compiles, but I get nothing when I jump into the BSL

My modified linker file:

-l msp430f5342.cmd

Any ideas about why this linker file is not working on a MSP430F5342?  I suspect some address and/or section definitions may be incorrect?

Thank you!

Hi William,

did you check the MSP-BSL landing page:

There is also a link how to customize a BSL and how to built and debug with CCS in the following document on page #23

Hope this helps!

Hello Dietmar,

Yes, I've gone through all of the custom BSL material, including the ones at the MSP-BSL landing page.

Yes, I followed the instructions in slaas450f Creating a Custom Flash-Based Bootloader.  Unfortunately, debugging in CCS shows no code was written to flash despite a successful compile with no warnings about overflows or overlaps.  There was no warning about a secured device.  JTAG lock key was present.

I suspect the memory map defined in the linker file I posted might be wrong, especially the definitions for the BSL area sections.  Can you please confirm the memory map, and the rest of the linker file, looks good?

Hi William,

your BSLSIG section has to include following information. Can you maybe sent the TXT file your compiled BSL code?

0x17FA BSL StartVector.This is the address of the first instruction to be executed when the BSL starts.

0x17F6 BSL UnlockSignature1. This word shouldbe set to 0xC35Ato indicate a correctly programmed BSL. If it is written with any other value,the BSL will not start.

0x17F4BSL UnlockSignature2. This word should be set to 0x3CA5 to indicate a correctly programmed BSL.If it is written with any other value,the BSL will not start.

Dietmar,

I do see my BSLSIG section contains just 0xFF bytes.  So there is no valid data in the BSLSIG section.  How can I write valid data into BSLSIG?  Do these bytes need to be defined somehow in the linker file?

I've attached the TXT file from the compiled BSL code.  I posted my linker file, which contains the BSLSIG section definition, in a previous posting.

Hi William,

simply take the BSL source projects. There the linker command files are included which have all the stuff you need. Out of this you can modify a project to your needs and then you have your own BSL. If import the CCS_v7_MSP430F543xA_TA_UART from this archive import it to CCS and build it I have the BSL mapped to the BSL memory.

Here is the TXT

Dietmar,

Yes, that's exactly what I did.  I imported the CCS_v7_MSP430F543xA_TA_UART project from the Custom BSL.  I built it and got the same TXT file you posted showing content in the BSL.

I then modified the linker file to fit the MSP430F5342.  Rebuilding gives the TXT file I posted showing nothing in the BSL except for 0xFF.  So something must be wrong with the linker file.  I'm just using the linker file from the CCS_v7_MSP430F543xA_TA_UART project with some modifications to fit the address map of the MSP430F5342.  Do you see anything obviously wrong with the linker file I posted?

If you don't see any problems, do you have a linker file for the MSP430F5342 that gives a working BSL which you're willing to share here?

Thank you,

- William

Dietmar,

I changed the FLASH section definition in my linker file back to the original:

FLASH                   : origin = 0x1042, length = 0x07AE

I also modified the ZAREA_CODE section definition right before FLASH to shorten the length and avoid an overlap:

ZAREA_CODE              : origin = 0x1014, length = 0x002E

This gives me a TXT file showing non-0xFF bytes in the BSL area!  So it looks like my BSL area was written.

However, the words at 0x17F4 and 0x17F6 do not show 0xC35A and 0xC35A like what the "Creatinga CustomFlash-BasedBootloader (BSL)" indicates should be there.  I also don't see what looks like a good address for the BSP protect function at 0xF7F2.  I don't see these words in the TXT file that you posted from the F5438A example in the Custom BSL so perhaps it's okay?

Also, I see the main() and other C functions from the Custom BSL example at address 0x10000 in the FLASH2 section.  Is this okay?  Shouldn't this BSL code be in the BSL Z-AREA in order to leave FLASH2 for user application code?

It looks like main() from the Custom BSL is running on my MSP430F5342.  I'll try talking to it now with BSL Scripter.

Thank you for your continued support.

Hi William

one possibility would be to define this in the linker file

    BSLSIG                  : origin = 0x17F0, length = 0x0002
    BSL_PROTECT             : origin = 0x17F2, length = 0x0002
    BSL_UNLOCK_1            : origin = 0x17F4, length = 0x0002 fill=0xC35A
    BSL_UNLOCK_2            : origin = 0x17F6, length = 0x0002 fill=0xC35A
    BSL_RESERVED            : origin = 0x17F8, length = 0x0002
    BSL_START               : origin = 0x17FA, length = 0x0002

Then it would appear in the TXT.

For the rest I will come back soon.

William,

what I find interesting is that if you use the IAR example out of the BSL example bundle a perfect BSL image is generated as shown below.

So maybe the CCS examples are not running with the latest CCS. May I ask which CCS version you're using?

I will go in contact with the people who developed the examples.

Dietmar,

I am using CCS version 9.3.0.

I appreciate you contacting the people who developed the examples.  Hopefully, they can explain why the IAR example works but the CCS example does not.  At least when modified for the F5342.

Regards,

- William.

Dietmar,

Also, the MSP430F543xA_TA_UART_IAR.txt TXT file shows no code at 0x10000.  Yet, the C code for the custom BSL example in CCS is being placed at 0x10000.  Is this yet another change I need to make to my linker file to put all of the custom BSL example code, including the C code, into the BSL?

Regards,

- William.

William,

I discussed with the experts and they are aware of this issue and work with priority to get it fixed.

It has nothing to do with your changes at all and the linker command file seems not to be the problem. The issue with current CCS versions is that the BSL_low_level_init file is not found within the CCS file structure on newer CCS version.

So as quick idea I can only recommend to use either IAR or CCS v7. But I will push for and updated BSL project release fixing these issues as soon as possible.

Dietmar,

So there *is* a problem with CCS and the Custom BSL example project.  I'm glad to hear the experts say there is indeed an issue and that they're working to fix it.

For what it's worth, I noticed BSL_Device_File.h is shown in the imported project Project Explorer but it doesn't actually exist in the file system.  I suspect this is what's giving a warning about "This project contains 1 unresolved buildable linked resource(s).  The project may not build as expected." when building.

I look forward to hearing back from you and the experts.

Regards,

- William.

Dietmar,

I tried the workaround in http://e2e.ti.com/support/microcontrollers/msp430/f/166/p/872514/3238096#3238096.  Unfortunately, I was unable to rebuild the libc.a library with a new boot.c that had the MPU functions commented out at the end so this workaround did not work for me.  Thus, I think I'll wait to get something from the BSL experts to test.

In the meantime, perhaps some of my other questions can be addressed?  Specifically, should the C code in the custom BSL example be placed at 0x10000 (FLASH2 section)?  If so, doesn't that overwrite any application code that may have been at 0x10000?  Shouldn't all of the custom BSL code be in the BSL section?

Thank you,

- William.

Hi William,

so with CCS it seems that the compiler has challenge to generate machine code which fits into BSL memory area. Normally all the should be located from 0x1000 to 0x17FF otherwise it will not work properly.

Historical BSL was developed on IAR therefore with IAR it works fine. So BSL experts work on getting the issues fixed so that we can compile a meaningful image and then compiler optimization can be checked to fit BSL binary into BSL memory section.

Dietmar,

So as suspected, all code, including the C code, for the custom BSL example (or any BSL) needs to fit into the BSL area from 0x1000 to 0x17FF.  No code should be at 0x10000.  That makes sense since I expect user application code to be at 0x10000, not BSL side.

I look forward to trying new code from the BSL experts whenever it is ready.

Regards,

- William.

Hi William,

want to give an heads up on schedule. Tentative release goal of new SW for BSL package is end of March.

Dietmar,

I appreciate the update about the schedule.  This helps with my planning.

I look forward to hearing something around the end of March.

Regards,

- William.

Hello Dietmar,

I hope you are safe.

Now that it is the end of March, I'd like to ask for an update on when new custom BSL software might be available to try with CCS?

Thank you,

- William.

Hi William,

thanks doing fine in these strange and crazy days hope you as well?
Thanks for follow up so I chatted with our BSL development person and we will release it to web this week. Actually we are in the approval process which is slightly delayed due to this strange corona situation. An update will be provided in the thread once it is available on the web.

Thanks for your understanding and patience on this.

Stay safe!

Hi William,

We are still waiting the publishing process at the moment. There are couple of internal new process that I need to go through to be able to get this update online. I'll keep you update on this thread until it gets published. I apologize for the delay from the date that we scheduled before. Stay healthy and safe.

Hi William,

the new update of the Custom BSL 430 is now online http://software-dl.ti.com/msp430/msp430_public_sw/mcu/msp430/MSPBSL_CustomBSL430/1_02_00_01/index_FDS.html  please refer to the section 1.3.3 on this application note http://www.ti.com/lit/an/slaa450g/slaa450g.pdf that to build the BSL image fits into BSL area, we need to limit the functionality of the BSL. however this is modifiable. let me know if you have further question.

Fatmawati,

I'm delighted to hear the Custom BSL update for the MSP430 is now online.  I will look it over and try it.  This may take a little longer than usual because I can get access to my lab and eval board only occasionally with stay-at-home restrictions in effect for my area.  I'll let you know if I can make more progress in CCS with this update.

Regards,

- William.

Fatmawati,

I tried compiling the new 1_02_00_01 Custom BSL code.  I get the warning below when I build the project with CCS v9.3.  Is this something to be concerned about?

#10247-D creating output section ".TI.noinit" without a SECTIONS specification

Regards,

- William.

Hi William,

apologize for late response on this. this warning should not affect the code. we can fix this warning by having additional:

    .TI.noinit  : {} > RAM                /* C I/O BUFFER                      */

under "SECTIONS" in the linker command file.
