m4ctl for i.MX8M Mini

m_c — Thu, 19 Sep 2019 12:17:51 GMT

There is an useful tool (m4ctl) for start/stop/deploy m4 from Linux but can't work on i.MX8M Mini.

We know there is an application note (AN5317) about similar function for i.MX6SX/i.MX7 can refered but just several detail steps instead of tool like above.

Is there simple command line tool like m4ctl for i.MX8M Mini?

Is there a standard implementation for the m4ctrl package for the i.MX8m mini?
Could I also get a copy of these files?

Hi Igor

I often see your comment that you are sending the information via e-mail instead of posting here. Is there a reason for not posting those. As this is an open forum it would be nice to have the information available for all of us. Perhaps some of the stuff you send privately is related to the security part of the SoC and probably not available for public. Is this the case with this one as well ?

Best regards

Hi Sinan

it may be suggested to create service request for such cases.

Hi Igor

Perhaps you misunderstood. I was just asking why you sometimes (and for this particular case as well) send the replies via e-mail instead of posting here so that everyone can have access to the information.

Hi Sinan

I fully understood your question.

Not all internal codes can be publicly shared.

Regarding this patch I asked owner of this application

what could be better option to proceed.

Hi Igor

Thanks for your time responding to this. I totally understand there are some information e.g related to security issues etc. that can't be shared publicly. In this particular thread it would be great If the author (Stefan) was able to share the files you send individually. As I can see there is at least 3 other people who were interested in this. I guess my point and suggestion is as an open forum, replies should be open to everyone as much as possible since otherwise it looses its meaning to be an open forum becomes more of a technical support portal. However here we all like to share our technical experiences and would like refer to previous threads when we come across with a new problem.

This is my 2 cents and thanks for your consideration.

Best regards

Hi,

I would also be interested in information about running m4ctrl on imx8mq.

Hi Igor,

access to the patch to use m4ctrl on i.MX8MQ would be very useful for me also, it would be great if this support gets added to the next release!

Best regards, Klaus

Alse need m4ctrl working on imx8mm

Can you send same code to me?

Re: m4ctl for i.MX8M Mini

dwainer — Mon, 21 Sep 2020 14:21:20 GMT

I am also interested.

I think we have enough requests in order to publish the i.mx8 mini support.

Dear Igor,

is it possible to obtain the patches and instructions for iMX8MM/iMX8MQ?

Are we supposed to sign any NDA?

Thanks

use the rpmsg_lite_str_echo_rtos M4 project, and the Linux side uses imx_rpmsg_tty.ko. 1: Normal uboot starts M4, after linux starts, load the module insmod imx_rpmsg_tty.ko 2: rpmsg str echo is normal 3: Use m4ctl in linux to reset M4 4: Uninstall the module rmmod imx_rpmsg_tty.ko 5: Reload insmod imx_rpmsg_tty.ko 6: The rpmsg str echo is abnormal, and the M4 is in an infinite loop while (!rpmsg_lite_is_link_up(my_rpmsg)); question1: How can I keep the rpmsg tty working normally after resetting M4 core using m4ctl in Linux?

Hi Igor,

We have a customer using Zephyr on the Cortex M4 and we could do with access to these utilities too.

Could you send me the files also please?

I switched to remoteproc for controlling Cortex-M4. It can load firmware as well as control the processor start/stop state. the task can be performed many times, switching from firmware to firmware without rebooting.
