NO 08:46 PM Software Development: Streaming from 5 cameras simultaneously: What is the status of streaming from 5 cameras simultaneously? Is this possible with software mods, or are there hardware limitations that prevent this? Nathan Olson

NO 08:50 PM Software Development: RE: Camera driver development: I removed the power-related fields because my camera is powered by an always-on supply, and I was trying to simplify things as much as possible. I'll try adding that stuff back, in particular @power-domains@ seems like it might be import... Nathan Olson
NZ 08:43 PM Software Development: RE: Camera driver development: Hi Nathan,
I too have noticed the probing of sensors 0-12, I have not looked into it but we see this same behavior. I expect your sensor to be 0.
If your sensor XML has the correct I2C address, I2C speed, sensor ID, and sensor ID r... Noah Zins
NO 01:06 AM Software Development: RE: Camera driver development: Thanks, Noah.
I'm trying to bring up a new sensor, and no luck so far. To simplify things, I've removed all camera modules except mine, and removed all multicamera configs except mine, which has a single camera at cameraId 0, slot 0, ... Nathan Olson

NZ 09:15 PM Software Development: RE: Camera driver development: Hi Nathan,
We used the r1.0_00095.0 release of Qualcomm_Linux.SPF.1.0|AP|Standard|OEM|NM_QIMPSDK for our firmware development. It contains the r1.0_00376 release of QCM6490.LE.1.0 where the meta-qcom-extras layer resides. These versio... Noah Zins

WE 12:21 PM PCB Development: RE: USB3 Data Port with External PD Control: Good morning David, I hope you had a good weekend!
I'm not super familiar with the kernel framework but I would think that it would get both the "role" the processor needs to be (either host or device) as well as the "orientation" of ... William Evans

DC 09:28 PM PCB Development: RE: USB3 Data Port with External PD Control: Hello William,
Thanks for your response!
Unfortunately we're locked into having the MUX/PD on the baseboard, so we can't continue down the easy path.
But I've checked and confirmed that the PD controller we are using exposes ... David Cuccia
WE 07:45 PM PCB Development: RE: USB3 Data Port with External PD Control: Hello David,
After thinking about this, here are my thoughts.
The MitySOM-QC natively supports USB 3.0 signal MUXing as well as USB PD. The simplest path, if you're not committed to the external PD/MUX, is to let the SOM handle bo... William Evans
NO 08:52 PM Software Development: Camera driver development: Do you have any resources to help with camera driver development? I've found Qualcomm's "Linux Build Guide", "Linux Camera Guide", and "Linux Camera Guide - Addendum". I'm now working on building the camera and sensor files from source.
... Nathan Olson

GG 08:53 PM Software Development: RE: UART bringup: Hi Nathan,
I am able to reproduce and it seems the issue is not with uart14, but rather with trying to instantiate more than 4 UARTs.
I have not yet found anything in Qualcomm's docs that explains such a limitation.
I will re... Gregory Gluszek
GG 03:13 AM Software Development: RE: UART bringup: Hi Nathan,
Nothing immediately stands out as to why you're having this issue (I have a project where I have success using this QUP for spi14 without issue).
I will try and reproduce your issue on my end and get back to you.
T... Gregory Gluszek

DC 09:45 PM PCB Development: USB3 Data Port with External PD Control: Hey Team,
I'm working on porting a hardware design for a custom carrier board to leverage the MitySOM platform. This carrier board owns the USB3 port's CC lines for PD negotiation and cable orientation detection. We don't need Displa... David Cuccia

NO 12:33 AM Software Development: UART bringup: I've got a device tree building for my carrier board, and a custom QUP configuration working! However, only 4 out of 5 of my UARTs are working. uart14 returns an error when it is probed. Here's the relevant output from dmesg: Nathan Olson

NO 06:58 PM Software Development: RE: Processor rebooting: Thanks Greg. I'll leave USB1 enabled for now as I work on bringing up other peripherals. I'd love to eventually figure out how to disable it, especially if that can result in any power savings. Nathan Olson
GG 06:34 PM Software Development: RE: Processor rebooting: Hi Nathan,
Thank you for all the information. We have worked with another design that also did not connect the SS lines for this USB and they have not had to make the same changes in the DTS (e.g. having usb_1_qmpphy enabled is not a... Gregory Gluszek

NO 11:24 PM Software Development: RE: Processor rebooting: I've narrowed it down even further. The problem does not occur if I use CriticalLink's QUPConfig and the following device tree: Nathan Olson
