LS2088A pinmuxing

pradeep_t — Tue, 02 Apr 2019 06:33:40 GMT

Hi Team,

We are using ls2088a in our board, can we get pin muxing details for LS2088ARDB and document for pin muxing in ls2088a.

For the LS2088ARDB please refer to the QorIQ LS2085A/LS2088A Reference Design Board Reference Manual, Chapter 3
Qixis Programming Model, 3.34 Board Configuration Registers.

For the LS2088A in general please refer to the QorIQ LS2088A Reference Manual and QorIQ LS2088A/LS2048A Data Sheet.

Please consider that CodeWarrior QorIQ Configuration and Validation Suite contains PinMuxing Tool for the LS2088A:

Hi ufedor,

After following document QCVS_PinMuxing_User_Guide.pdf i am not able to generate the report using QCVS Version: 11.4.0
Build Id: 190130.

HI Ufedor,

Attached ZIP file with pics, Their are no problem in QCVS for generating or build but its not generating the PINMUX report

ufedor — Thu, 04 Apr 2019 12:02:42 GMT

Where is the QCVS project?

Re: LS2088A pinmuxing

PFA, I have made zip of complete QCVS project

Thank you for the support,

Do we need to use QCVS 4.16.0

Re: LS2088A pinmuxing

ufedor — Thu, 04 Apr 2019 12:32:36 GMT

Yes.

Hi Ufedor,

Can we get link for

QCVS 4.16.0 we are using ubuntu 18.04.

Please try to use Help -> Install New Software -> select "--All Available Sites--" and check whether the QSVS update is available for your version of the CodeWarrior.

Hi Ufedor,

Any document for pinmuxing in uboot and kernel for lsdk 18.09

Re: LS2088A pinmuxing

ufedor — Tue, 16 Apr 2019 09:09:57 GMT

There are no additional documents to the QorIQ LS2088A Reference Manual and QorIQ LS2088A/LS2048A Data Sheet.

Hi ufedor,

We are able to generate PINMUX report in both xml and HTML. Can you help ,how to use this report for our custom board and where to include?

Re: LS2088A pinmuxing

Current version of the PinMux Tool allocates selected modules/signals and checks that the projected combination of modules/signals could be implemented in general.

It is required to use PBL Tool to implement the desired multiplexing in RCW.

It is required to use PBL Tool to implement the desired multiplexing in RCW.

For doing PIINMUX in RCW there is pinmultiplexing configuration field [302-825]. Here iam able to configure some of pins.

1. Iam not sure how to use this generated pinmux report in our custom board?

2.Is there any reference to do pinmux in u-boot and kernel?

Pin multiplexing is possible only in RCW.

By design it is impossible to alter pin multiplexing during run-time.

Hi ufedor,

We want to make following pins as GPIO in RCW .

TSEC_1588_PULSE_OUT2,

TSEC_1588_PULSE_OUT1,

TSEC_1588_CLK_OUT,

TSEC_1588_ALARM_OUT2

TSEC_1588_ALARM_OUT1

TSEC_1588_TRIG_IN2

TSEC_1588_TRIG_IN1

TSEC_1588_CLK_IN

But we dont find any filed in RCW related to above pins in codewarrior. Kindly help us where we can modify.

Re: LS2088A pinmuxing

ufedor — Mon, 29 Apr 2019 11:40:59 GMT

The pins are controlled by the RCW[832]
