MCU-PLUS-SDK-AM243X: SysConfig "Additional ICSS Settings" GUI for PRU IO configuration not available for am243x-lp (or boards based on that device pinout)

Steve Squires

Part Number: MCU-PLUS-SDK-AM243X
Other Parts Discussed in Thread: SYSCONFIG

I just discovered the new SysConfig "Additional ICSS Settings" field with the AM64X SDK 8.2. It looks to be exactly what I need to configure the PRU IO via a GUI instead of painstaking and error-prone pinmuxing in assembler. Awesome!

However, this feature does not appear to be available for the AM243x-lp devices (it's excluded from C:\ti\mcu_plus_sdk_am243x_08_02_00_31\source\drivers\.meta\pruicss\g_v0\pruicss_g_v0.syscfg.js).

When might we be able to use SysConfig to define the PRU IO for all variants of the AM243x?

Thanks, Steve

Hi Steve,

It looks like this feature was also present in AM243x/AM64x MCU+SDK 08.01.00.36.

I also see the AM243x LP is excluded from having this feature.

<SDK>/source/drivers/.meta/pruicss/g_v0/pruicss_g_v0.syscfg.js:

                let modInstances = new Array();
                if((device === "am64x-evm") || (device === "am243x-evm"))
                {
                     modInstances.push({

                         displayName: "Additional ICSS Settings",
                         moduleName: '/drivers/pruicss/pruicss_gpio',
                         useArray: true,
                         minInstanceCount: 0,
                         defaultInstanceCount: 0,
                     });
                }

            function moduleInstances(instance) {

                let modInstances = new Array();
                if((device === "am64x-evm") || (device === "am243x-evm"))
                {
                     modInstances.push({
                         name: "AdditionalICSSSettings",
                         displayName: "Additional ICSS Settings",

                         minInstanceCount: 0,
                         defaultInstanceCount: 0,
                     });
                }

I don't know why the LP is excluded. I'm looking into this and will get back with you shortly.

Hi Steve,
As Frank mentioned, the check for device === "am243x-lp" got missed from the conditional. Please add it as below in

<SDK>/source/drivers/.meta/pruicss/g_v0/pruicss_g_v0.syscfg.js:

Thanks for communicating the bug.

Hi Himanshu - I already figured this out

However, I can't get SysConfig to generate the required ti_pru_io_config.inc file.

(FYI I'm using hello_world_am243x-lp_r5fss0-0_nortos_ti-arm-clang example.syscfg)

How can I do this?

Thanks, Steve
