Other Parts Discussed in Thread: AM2432, SYSCONFIG

I am working on a AM2432 with mcu_plus_sdk_am243x_08_05_00_24

Which is the procedure to modify PLL in order to have a lower power consumption ?

Is it something controlled by Syscfg ?

Is it related to SysFw configuration ?

Thank you in advance

Hey Andrea,

I wanted to point out that mcu_plus_sdk_am243x_08_06_43 is now available.

Download Link: MCU-PLUS-SDK-AM243X Software development kit (SDK) | TI.com - .exe direct link

TI provides TICSI API for configuring device clocks (see TISCI PM Clock API Documentation — TISCI User Guide).

SysConfig can be used to configure peripherals to operate at a given frequency, but the TISCI API functions are used to configure the clock sources.

There is also additional information regarding PLL configurations in the Device Configuration - Control/Clocking chapters of the TRM.

Best Regards,

Unfortunately I cannot find SoC Family Specific Documentation for AM243x

By the way, examples I found in the SDK/drivers/sciclient include configuration messages in HEX form.

How about to generate those hex files ?

Looking forward

Hello Andrea,

AM243x uses the same SoC Family Specific Documentation as the AM64x device. The only exception is that anything related to A53SS/GIC is unsupported in AM243x devices.

The bin2c.py script is used to generate the hex files and is described in the link below:
