[FAQ] MCU-PLUS-SDK-AM243X: R5F MPU configuration in MCU+ SDK

MCU-PLUS-SDK-AM243X: System Ticker Timer for AM243x MCU R5 Core

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

Hello,

From the AM243x MCU technical manual, there are 3 different types of timer module available for R5 core, Global Time Counter (GTC), Windowed Watchdog Timer (WWDT) and the general purpose timer (TIMER). We need to create a system ticker timer as the task scheduler, which type of the timer I should choose?  In addition I have tried to use SysConfig tool to add a system ticker timer, but when I select device AM243x_ALX_beta, there is no GTC and WWDT peripherals. Could you please advise which type of timers are the right one for system ticker and how to create it for AM243x with the SysConfig tool.

Thanks,

Zhuying

    A general purpose timer would be best, but as far as system tick timers for task schedulers go, the SysConfig generation should already provided a 1ms sys tick timer - review the details under the Clock option in SysConfig.

    If you need a second clock beyond that for some reason, make a new TIMER instance for use.

    Which version of SysConfig, AM24x SDK, and CCS are you using? I have not seen these absent for the AM243x_ALX_beta package.
