AM2434: How to configure GPIO MUX INTRTR0 router

Hi Bolt,

I was able to get this working in SDK 08.05 by hacking at it. Perhaps something isn't properly configured on my PC (e.g. node.js). I'll follow up with the SW Dev team to better understand how this is supposed to work.

Steps I followed:

#1: Modify resource allocation

See https://software-dl.ti.com/mcu-plus-sdk/esd/AM243X/08_05_00_24/exports/docs/api_guide_am243x/RESOURCE_ALLOCATION_GUIDE.html

Assign all Interrupt Router outputs to R5F0_0 in sciclient_defaultBoardcfg_rm.c (attached below).

#2: Rebuild SYSFW board configuration

See https://software-dl.ti.com/mcu-plus-sdk/esd/AM243X/08_05_00_24/exports/docs/api_guide_am243x/TOOLS_SYSFW.html#BOARCFG_GEN

I'm using SBL NULL, so I had to rebuild it as a final step and reflash it to the LP:

gmake -s -C examples/drivers/boot/sbl_null/am243x-lp/r5fss0-0_nortos/ti-arm-clang all

Note the docs have "gmake -s libs" as the build command for the SBL, which is incorrect.

#3: Modify C:\ti\mcu_plus_sdk_am243x_08_05_00_24\source\drivers\.meta\gpio\soc\getBoardConfigRm.js (attached below):

• Remove "am62x" from boardConfigSocList. Without this change, if I click on "GET RM DATA" in Sysconfig, I see: 

• Set board data output file as follows: outFile = "k3BoardConfig.json"
  • C:\ti\mcu_plus_sdk_am243x_08_05_00_24\source\drivers\.meta\gpio\v0\gpio_v0.syscfg.js expects the board data in this folder/file. With the default definition of "outFile", the k3BoardConfig.json file isn't updated.
  • With this change, "GET RM DATA" will generate "k3BoardConfig.json" in the Debug folder of the CCS project. Copy the generated "k3BoardConfig.json" to C:\ti\mcu_plus_sdk_am243x_08_05_00_24\source\drivers\.meta\gpio\soc.

#4: You can now select any of the 16 router output in Sysconfig and recompile the application.

Frank

Hi Bolt,

Because I don't know how to get RM Data in Sysconfig,

Click on the "GET RM DATA" in Sysconfig, GPIO configuration.

Reference your step, which step would be happend the bug: MCUSDK-9398? 

There are two related issues I filed for this bug:

1. GET RM DATA doesn't work unless "am62x" is removed from boardConfigSocList in getBoardConfigRm.js
2. getBoardConfigRm.js for Sysconfig interface to GPIO driver doesn't get updated board configuration data. Becuase of this, getBoardConfigRm.js can reject updated IR routes as being unavailable.

Bolt Hsieh said:

So, if I use SDK 8.5.0.24 and follow your step, I still can't configure GPIO MUX INTRTR0 router success, is right ?

You should be able to configure the IR routes in SDK 8.5.0.24 if you follow my steps.

Hi Bolt,

Can you please try adding this to your system path?

<CCS_ROOT>\ccs\tools\node

Please let me know if this works. I don't see setup for node mentioned in the SDK setup docs.

Frank

Hi Bolt,

But, If I put the path to top, Sysconfig will open fail. So, I put the path to bottom.

Thanks for sharing this observation. I also have C:\ti\ccs1210\ccs\utils\bin before the node path in my system path.

I get the information of SCI event config failed when I run the .out in AM243x launch pad

In addition to the steps I outlined above for "GET RM DATA", please be sure you carefully follow the steps in these docs: https://software-dl.ti.com/mcu-plus-sdk/esd/AM243X/08_05_00_24/exports/docs/api_guide_am243x/TOOLS_SYSFW.html#BOARCFG_GEN

If you're using SBL NULL for SOC initialization, be sure you reflash SBL NULL to the LP as documented here: https://software-dl.ti.com/mcu-plus-sdk/esd/AM243X/08_05_00_24/exports/docs/api_guide_am243x/EVM_SETUP_PAGE.html#autotoc_md26

If you're using CCS scripts for SOC initialization, be sure you properly update the sciclient_set_boardcfg application .out file. Copy

• from <SDK>\examples\drivers\sciclient\sciclient_set_boardcfg\am243x-lp\r5fss0-0_nortos\ti-arm-clang\sciclient_set_boardcfg.release.out
• to   <SDK>\tools\ccs_load\am243x\ folder.

If your application is in Debug build mode, it will link the Debug libraries, so I recommend building debug and release libraries as follows:

• release: gmake -s libs
• debug: gmake -s libs PROFILE=debug

I was able to change the GPIO example to use ROUTER7 output:

I've attached the complete CCS project below.

Let me know how it goes.
