devregs support for 6sololite

jayakumar2 — Fri, 12 Jun 2015 06:24:10 GMT

Hi fsl friends,

I'm using a 6sololite based board. I noticed the devregs tool which I think could be really useful. I checked out the tree at : devregs/dat at master · boundarydevices/devregs · GitHub

But I can't seem to find a DAT file for 6sololite. In particular, the EIM and EPDC registers would be pretty useful to me. I am curious if the dat file maybe hosted somewhere else and I just haven't found it. Otherwise, I suppose I could generate it using the kernel headers but it is probably a decent amount of work.

Thanks,

jayakumar

Hi Jaya

for devregs usage one can look at

devregs - tool to display and modify a device's registers at runtime

probably you may wish to use imx-test/memtool

http://repository.timesys.com/buildsources/i/imx-test/imx-test-3.14.28-1.0.0/

Best regards

igor

Igor,

Thanks for your reply. But I think you may have misunderstood my question. I'm not asking how to use devregs, I've used it before. I've repeated my question below:

I can't seem to find a DAT file for 6sololite. In particular, the EIM and EPDC registers would be pretty useful to me. I am curious if the dat file maybe hosted somewhere else and I just haven't found it. Otherwise, I suppose I could generate it using the kernel headers but it is probably a decent amount of work.

So my question is about the DAT file for 6sololite devregs. Yes, I understand I could make it myself. I already use memtool currently and I'm looking for something better with named registers and bitfields which is what devregs does.

Thanks,

jaya

Jaya

this utility was provided by boundary devices,

so proper way to post this question on its forum or

meta-fsl-arm mailing list, so that someone familiar with that

particular BSP could try to assist you

Hi Jaya,

Igor is right (this tool was authored by Boundary Devices), but it's also on Github for a reason (so that others can contribute).

We update it when we're working on different processors (and will do so with i.MX6 SoloX soon).

We don't have plans to release a board with the i.MX6 SoloLite, so I'm afraid we won't be adding .dat files for that processor.

I can offer insight into how we and others have gathered this information:

Use pdftotext on the reference manual, then use your favorite text editing tool to grab the bits of interest, and/or
Use the .xml files in the IOMux tool, and/or
Use header files like this one:
https://github.com/boundarydevices/linux-imx6/blob/boundary-imx_3.10.17_1.0.2_ga/arch/arm/boot/dts/imx6sl-pinfunc.h

I hope this helps.

Eric
