Part Number: TMS320F28377S
Other Parts Discussed in Thread: C2000WARE, SYSCONFIG

Tool/software:

Hi champs,

Customer report when they enable HWPWM option in syscfg, they can not choice EPWM4/EPWM5.

[Development Environment]

C2000Ware version: 5.03.00.00 (latest)
SysConfig version: 1.21.1.3772 (latest)
CCS version: 12.7.1.00001

[Issue] When using the latest SysConfig, whether standalone or embedded in CCS, can not enable EPWM4 and EPWM5 as HRPWM.

Once HRPWM is disabled, PWM module can be assigned to any one.

This can't match device datasheet as EPWM4/5 can be used for HRPWM.

Can you please help to check and provide solution? Or any special reason to disable HRPWM function for EPWM4/5?

Regards

Andre

Luke Jones, Siddharth Deshpande,

Looks like something in the pinmux.js file which limits the HRPWM selection. Please review asap.

Hi Andre,

This is a mistake in C2000Ware 5.03. I've tested this using C2000Ware 5.02 and EPWMs 1-8 all have HRPWM support which matches the datasheet. This will be corrected in the next C2000Ware version.

For now you can correct this in C2000Ware 5.03 by replacing the pinmux.js file in C:\ti\c2000\C2000Ware_5_03_00_00\driverlib\.meta\ with the following file:

2068.pinmux.js

Thank you,

Luke
