How to enable GPIO header J10 (GPIOEVT[1:5]) on the LX2160A-RDB-B ?

ajedgar — Wed, 19 Apr 2023 23:58:23 GMT

We want to enable the GPIO header J10 on the LX2160A-RDB-B board.

It looks like the GPIO pins at J10 (GPIO/EVT[1:5]) are disabled by default.

So far it seems the only way to enable them is by re-flashing the RCW.

A couple of questions, is this true? Is there no other way to enable GPIO at J10 at run time? With DIP switches?

If I don't have Code Warrior what is the simplest way to create a new RCW and flash it?

It looks like there is a way to set the RCW using the Lauterbach debugger, does anyone have an example script for this?

Many thanks in advance for any and all pointers!

You could refer the board reference manual for the details information.

If you use LSDK, you could try to use commands below to generate RCW binary file:

$ git clone https://github.com/nxp-qoriq/rcw
$ cd rcw
$ git checkout -b LSDK-21.08 LSDK-21.08
$ cd LX2160axxx
If required, make changes to the rcw files.
$ make

You could use the generated binary, confirm the */flexbuild_lsdk2108xxx/configs/board/lx2160axxx/manifest select rcw_xspi, rcw_xspi="path/*.bin"(make sure the path is the required bin file)

$ cd ~flexbuild_lsdk2108xxx/
$ source setup.env
$ flex-builder -i clean-firmware
$ flex-builder -c atf -m lx2160axxx -b xspi
$ flex-builder -i mkfw -m lx2160axxx -b xspi

Now the required xxx image is available in*/flexbuild_lsdk2108xxx/build/images

The Lauterbach TRACE32 offers two methods to change the RCW.

A temporary change of the RCW is possible using the RCW override feature. This is also helpful to connect to the processor there is not RCW programmed to flash yet. The script lx2160-spi-rcwovr.cmm shows how to do this.

For a permanent change, the RCW needs to be programmed to the flash selected as boot source. Above script also sets up the FLEXSPI for programming. If booting from other boot source, a different script will be required.

Thank you Reinhard. I'll give that a try.

Thank you June Lu.

The manifest file for the lx2160ardb_rev2 the exists:

$ pwd

$ /home/ajedgar/shared/flexbuild_lsdk2108_github

$ ls -l configs/board//lx2160ardb_rev2/manifest
-rwxrwx--- 1 root vboxsf 8998 Aug 29 2021 configs/board//lx2160ardb_rev2/manifest

And looking inside we see the path to the RCW file I'm looking for:
$grep rcw_xspi configs/board//lx2160ardb_rev2/manifest
rcw_xspi="firmware/rcw/lx2160ardb_rev2/XGGFF_PP_HHHH_RR_19_5_2/rcw_2200_750_3200_19_5_2.bin"

But it doesn't yet exist (also looked under 'build' and 'packages' so presumably it has to be built:

$ ls firmware/rcw/lx2160ardb_rev2/XGGFF_PP_HHHH_RR_19_5_2
ls: cannot access 'firmware/rcw/lx2160ardb_rev2/XGGFF_PP_HHHH_RR_19_5_2': No such file or directory

When I try to do anything with flex-builder I get this:

$ flex-builder -i clean-firmware
ln: failed to create symbolic link '/home/ajedgar/shared/flexbuild_lsdk2108_github/build/linux/kernel': Operation not permitted

I added a couple of 'echo's to the flex-builder script and see:
FBOUTDIR: /home/ajedgar/shared/flexbuild_lsdk2108_github/build
KERNEL_TREE: linux

And here is how I created my setup (with the same result):

On Ubuntu 20:
$ sudo apt update
$ sudo apt -y upgrade
$ sudo apt-get install git

$ tar xvzf flexbuild_lsdk2108.tgz

$ source setup.env
$ flex-builder -i mkrfs -a arm64

$ flex-builder -i mkrfs -a arm64
ln: failed to create symbolic link '/home/ajedgar/shared/flexbuild_lsdk2108_github/build/linux/kernel': Operation not permitted

So presumably the KERNEL_TREE var in the flex-builder script is incorrect or I am missing a step.

Thoughts?

Many thanks in advance for your help!

A related question. I am trying to write directly to the FlexSIO to update the EVT20_PMUX and EVT32_PMUX bits as shown below. The 'mw' command says the bytes were written ok but when I read them back they are unchanged. This leads me to believe there must be some write-protection that needs to be disabled or I am missing a step or two. What is the best way to accomplish this?

Before changing the RCW, you should make your Host system can compile the image successfully(using the default source files). Please refer to LSDK21.08 4.1.1 Host system requirements, make sure your system can access server.

Download flexbuild_lsdk2108_github.tgz from nxp.com

tar xvzf flexbuild_lsdk2108_github.tgz

source setup.env

Hi June Lu,

Please see my comment below from yesterday (4/24) where I explain that I have downloaded 21.08 and followed the instructions but as soon as I try and do anything with flex-builder I get this error:

$ flex-builder -i mkfw -m lx2160ardb_rev2
MACHINE: lx2160ardb_rev2
ln: failed to create symbolic link '/home/ajedgar/shared/flexbuild_lsdk2108_github/build/linux/kernel': Operation not permitted

Am I missing something? Is there a "getting started" guide?

Thank you for your help!

Once I have successfully built an rcw.bin file how do I flash it to FlexSIO? Is there some documentation on this?

Thank you.

It seems you select flexbuild_lsdk2108.tgz rather than flexbuild_lsdk2108_github.tgz.

LSDK Repositories has migrated from CodeAurora to GiTHub, please use the flexbuild_lsdk2108_github.tgz.

Of course, if you renamed the file, I think it's OK.

I have checked the command:

$ flex-builder -i mkfw -m lx2160ardb_rev2

It works well in my Host system, maybe will need try some times because of the network. I think you need to check your Host system, I am sorry I could not help for that.

If you get a bin, you need to generate the image to program.

You could refer Layerscape Linux Distribution POC User Guide, Rev. L5.15.71-2.2.0 page 100 for XSFPI image program.

For the SD card and eMMC, you could refer page 103.

Hi June Lu,

I'm sorry but this is not a very helpful answer.

I am on Ubuntu 20.04 LTS. I have ensured that I have all the required packages installed per page 2 of this doc:
https://www.nxp.com/docs/en/user-guide/LLDPUG_RevL5.15.71-2.2.0.pdf

The packages that were not already installed that I had to install were: socat, python3-git, python3-jinja2, libegl1-mesa, libsdl1.2-dev, pylint3, xterm, python3-subunit, mesa-common-dev, zstd, and liblz4-tool.

Installing these packages made no difference in the behavior of the flex-builder. It failed in the same way described above.

I have re-downloaded and re-installed from the link you provided here: https://lsdk.github.io/components.html

And I still cannot get a clean build.

Can you do a new download from that link and try a clean test build of lx2160ardb_rev2 and let me know if that works for you?

Is there someone else at NXP you can talk to that can help? I really need to get this working.

In the mean time I will dig into it and see if I can figure out what is broken.

Thank you for your assistance.

best,
Andrew

Hi June Lu,

Also please keep in mind that all I am trying to do is update the RCW on the LX2160A-RDB-B rev2 board.

I have already figured out how to build a new RCW manually. Now all I need to do is update the FlexSIO flash with the new RCW.

I have tried writing directly to the FlexSIO using u-boot 'sf' command but it does not work. Is there some write protection that needs to be disabled?

Can you please point me to some detailed step-by-step instructions on how to update the RCW? And also how to write directly to the FlexSIO from u-boot using the 'sf' command?

Thank you for your assistance!

best,

Andrew

I have done a new download from the link and try a clean test build of lx2160ardb_rev2. it works well.

When I failed to create the ATF, I will input the command again(flex-builder -c atf -m lx2160ardb_rev2 -b xspi), the command will start to continue, until get a ATF.

When you get ATF successful, you could get the next step(e.g. flex-builder -i mkfw lx2160ardb_rev2 -b xspi).

When build the firmware, the command(flex-builder -i mkfw lx2160ardb_rev2 -b xspi) also need to input sometimes. I think it would be network link error.

Hope this will help you.

Anyway, the commands work well in my host system.

If you get an image, you could program it.

You could refer Layerscape Linux Distribution POC User Guide, Rev. L5.15.71-2.2.0 page 100 for XSFPI image program.

For the SD card and eMMC, you could refer page 103.

Hi June Lu,

After updating configs/sdk.yml and with the correct xserver URL and gitlab URL as below:

I need a new suggestion on how to progress past this point.

Command $ flex-builder -i repo-fetch

Didn't mention in this case.

Maybe it's from other case support.

I could use the commands above, please follow the my suggestion and try it.

Hi June Lu,

Which suggestion did I miss?

As I have said I have redownloaded from scratch and followed your instructions with the same result each time.

There is nothing new since you replied with,
"All commands you used workswell in my Host system, maybe will need try some times because of the network. I think you need to check your Host system, I am sorry I could not help for that"

I need a new suggestion.

Thank you.
