LP-AM243: Using XiP for singlecore application

Hi Jan,

Thanks for your query.

I have taken your inputs and working on it. Please allow some time to revert back.

Hi Jan,

Can you please confirm, have you followed all the steps properly?

Have you kept the main symbol inside MSRAM memory?

Have you also kept the -llibsysbm.a<trgmsg.c.obj> (.text) inside MSRAM if CCS prints are used?

Please refer below image.

Regards,

Tushar

Hello Tushar,

Yes I followed these steps, but I’m not entirely sure if I did everything correctly.

For .text I have it in flash as I dont use debug functions and when I try to move it to MSRAM, nothing changes.

For main symbol I didn’t find any information about it so I’m only guessing. From what I know it should be in MSRAM as only .text a .rodata are in FLASH. Here are data from map file in which I can see that boot is in MSRAM

From .out file I can see that part of code is defined for MSRAM

Are there any steps I can make to be completely sure that I have set it up correctly?

Thanks.

Best regards,

Jan

Hi Jan,

Can you please share the example.syscfg file with us?

Also please tell us which example are you trying to run?

Tushar

Hello Tushar,

Here is whole project with flash scripts I'm testing it with.

Hi Jan,

Thanks for sharing the above project.

I will try to replicate the issue at my end and will update.

Hello Tushar,

I'm having some issues running gmake as it has wrong path for "C:/ti/ccs1281/ccs/utils/cygwin/rm".

In my file system I have ccs1280 not 1281 and I can't find way to change this path. Is there any way to change it?

Best regards,

Jan

Hello Tushar,

I've tried your example and I can run it from CCS, but when I try to use it with sbl it doesn't start the program after power cyclce. I use sbl_ospi.cfg in FlashingTool file in project I shared but with new sbl files after recompiling SDK using commands you shared with me.

Best regards,

Jan

Hi Jan,

Are you able to see the complete SBL logs after powering the EVM?

Can you please send the logs from SBL?

Regards,

Tushar

Hello Tushar,

this is from 2 power cycles  

When i use it without XiP to run from RAM it works fine.

Best regards,

Jan

Hi Jan,

Is the above error coming from SBL OSPI example's main.c file?

Are you trying to say when all code is kept inside MSRAM through Sysconfig?

Can you send complete logs when the SoC boots?

above error is from sbl_ospi.debug.hs_fs.tiimage from file SDK\tools\boot\sbl_prebuilt\am243x-lp

yes

This is all I get from UART, is there a other way to get more detailed log?

Hi Jan,

It seems your SBL example code itself is failing. Can you please confirm have you made any changes in the SBL example?

It seems to fails after the Drivers_open() call. Can you please debug the SBL example?

Please refer faq-am62x-am64x-faq-debugging-sbl-boot-in-rtos-sdk for details on debugging SBL.

Tushar

Hello Tushar,

Sorry for late response.

I've tried reinstall SDK from https://www.ti.com/tool/MCU-PLUS-SDK-AM243X to make sure I have default files and tried run your example again with similar results. When I try to debug SBL I get stack on line 661 in sciclient.c

Where in this function which is called I get this:

When I tried to jump over this function I now don’t get any error with drivers_open but I get this to this line:

And now I get this log:

When I try using XiP example from mcu_plus_sdk_am243x_10_01_00_32\examples\kernel\dpl\xip_benchmark i get this errors:

. Is there any possible issue with me using CCS Version: 12.8.0.00012 with sysconfig version 1.22.0? 

edit: 

here is my SBL example project if it can help with resolving this issue

4812.sbl_ospi_am243x-lp_r5fss0-0_nortos_ti-arm-clang.zip

Best regards,

Jan

Hello Tushar,

I tried to get new versions of CCS and configure my setup according to software-dl.ti.com/.../GETTING_STARTED.html

When I tried running your commands and example again I still had to change imports paths even with everything installed to default paths. Is this behavior OK? Here is my imports.mak if it could be some issue there

0728.imports.zip

and here is my TI root file

:

Best regards,

Jan

Hi Jan,

Can you please share the sbl_ospi.cfg file which you are using with us?

Regards,

Tushar

Hello Tushar,

I shered whole SBL project here

Hi Jan,

Thanks for sharing the above project. I will check this.

I was asking for sbl_ospi.cfg file not the SBL project. Can you please share the configuration file?

I will provide you mine SBL binary and cfg file which you can check at you end and update me with results.

Regards,

Tushar

Hi Jan, 

Please refer below files.

SBL Binary - sbl_ospi.release.hs_fs.tiimage

Ospi Cfg - default_sbl_ospi.cfg

Sorry i misunderstood here is cfg file

 sbl_ospi.cfg

Best regards,

Hi Jan,

I have checked your cfg file and it looks okay.

Can you please check once with the files I have provided above?

Tushar

Hello Tushar,

I tried using your bootloader got this from UART but LED is still not blinking:

When I tried connecting to MCU with debug it got to HwiP_user_undefined_handler_c. I'll do more debuging and will share results. 

Best regards,

Jan

Hi Jan,

The SBL example is now working fine. Have you done any changes in the GPIO example?

Are you running mine GPIO example and still facing the issue? because on my end with the same binaries I can see LED blinking.

Regards,

Tushar

Hello Tushar,

I'm using your example without changes, And I'm getting HwiP_user_undefined_handler_c with first function call (System_init).

Could you share with me sbl_uart_uniflash? It's only bin right now that I'm using from downloaded SDK and not which you shared with me.

Best regards,

Jan

Hi Jan,

The uart uniflash is unlikely to create issue here. 

Uart_uniflash - sbl_uart_uniflash.release.hs_fs.tiimage

Can you please check with different EVM's as well?

Regards,

Tushar

Hello Tushar,

I don't have second LP kit to try same binari od different HW. But I tried using XiP on TMDS243EVM. It's with different binaries but facing same issue with bootloader not working

Best regards,

Jan

Hi Jan,

In the project which I shared there might be prebuilt binaries also which is working for me. Can you try those binary in gpio example's Debug folder without recompiling?

I can see with the SBL binaries provided above you were able to run SBL, and your application is not running.

Can you try the steps mentioned at Debugging XIP Application to debug the GPIO application?

I will be out of office from tomorrow till next week's Friday. So responses to this thread will be delayed. Thanks for your patience.

Regards,

Tushar

Hello Tushar,

I did try uploading your binaries without recompilation. As for debuging GPIO application I had issued I mentioned where I get HwiP_user_undefined_handler_c with first function call in project.

Best regards,

Jan

Hello Tushar,

I've tried on second LP kit with same result. For loading application I do this steps:

Set UART boot mode

Load binaries using:

Then switch to SPI boot mode: 

And this is boot log I get:

When i tried debug on both boards I got HwiP_user_undefined_handler_c when I tried to step into System_init();

Which is first function after blocking loop and  I couln't find any information what could cause this behaviour.

Here are bineries I got shared here and flashing tools I use:

flash.zip

And those are board IDs I'm using if it could by faulty series

Best regards,

Jan

Hello Tushar,

I’ve managed to resolve this xip issue by moving only some parts of code to XiP. Thank you for your assistance and patience.

regards,

Jan
