CCS/TMS570LC4357: doc / hw / sw issue with onboard CPU temperature sensors pinmux setting

Part Number: TMS570LC4357

Tool/software: Code Composer Studio

Hi Guys,

I'd like to ask if somebody experienced the following problem with onboard CPU temperature sensor pinmux settings:

According to spnu563 page 320 - (After kickoff) I tried to setup PINMMR173[17:16] = 0x2 to switch to the Temp 1 sensor - without any success,

although the temperature meassurement itself seems to work (see the attached screenshoot). The situation is same with temp 2 and 3 sensors.

Regards, Szilárd

    Hello Szilard,

    We have an appnote and example code for settup of the temp sensors included. It is available at this link: www.ti.com/.../spna216.pdf

    I am uncertain but from the appearance of your screen shot it seems the IOMM registers remained locked and that you have not enabled access to them using Kicker0 and Kicker1 registers as noted in the application note. Also note that the temperature sensors have to be enabled using IOMM174 as described in the application note.
