CC2674R10: the sensor controller can use pins DIO0-2, despite the compiler objecting

Olivier Naudan

Part Number: CC2674R10
Other Parts Discussed in Thread: CC2652R7, CC1354R10

* Context: on our custom PCB, we have unsoldered CC2652R7 and soldered CC2674R10 in place. Our plan is to update the software *without* modifying the hardware. We are using simplelink_cc13xx_cc26xx_sdk_7_10_02_23 and sensor_controller_studio_cli 2.9.0.208
* On CC2652R7, the sensor controller is using pin DIO1.
* When migrating to CC2674R10, the Sensor Controller Studio does not allow to select pins DIO0-2, the list starts at DIO3. If we modify directly the .SCP file to force DIO1, the compiler objects: ERROR: I/O function "SPI SCLK" is not mapped to a suitable pin
* However, if we modify directly the generated file, scif.c, then it seems to work: the CC2674R10 sensor controller successfully uses pin DIO1.

Bottom line: it seems to be a toolchain bug, not an actual hardware limitation. Can you please confirm?
If so, please consider updating the Sensor Controller Studio and CLI.

Hi Olivier,

I am not observing similar behavior from my end. Please make sure that you have installed all update patches in SCS and that the CC2674R10 device is selected (the behavior appears more related to a CC1354R10 configuration). Note that the latest SCS update supports SimpleLink CC13xx/CC26xx SDK v7.10.00.98

Regards,
Ryan

Hi Ryan,

Thank you, installing the patches on SCS for Windows solve the problem: DIO0-2 are now usable. However, in production, we are using the SCS CLI on Linux.

According to https://software-dl.ti.com/lprf/sensor_controller_studio/docs/cc13x2_cc26x2_help/html/command_line_interface.html, the "CLI for Update Service" is not available on Linux. For now we are stuck with version 2.9.0.208 and no patches, as confirmed by:

$ ~/ti/sensor_controller_studio/bin/sensor_controller_studio_cli --version
VERSION: 2.9.0.208
PATCHES: None

Is there a way to update SCS CLI for Linux as well?

Regards,

-- Olivier

Here is a prior E2E thread which explains how to work around this condition.

Thanks again, it works. Now SCS CLI for Linux is on par with SCS CLI for Windows.

Note that it would be easier if all patches were included in the latest downloadable SCS ;-)
