NO 03:46 PM Software Development: RE: Long build times: That matches what I'm seeing, although it seems your machine is much faster than mine. For me it's about 7 hours for a clean build, and 28 minutes for a rebuild. Nathan Olson
GG 02:36 AM Software Development: RE: Long build times: Hi Nathan,
We have similar experiences. Unfortunately we do not currently have a fix. We are building off of Qualcomm's methodology and there is a lot of complexity there that we haven't needed to dig into yet. We will update this is... Gregory Gluszek
GG 02:42 AM Software Development: RE: Configuring the QUP pins: Hi Nathan,
Please refer to the [[Configuring the QUP Ports (I2C I3C SPI and UART)]] wiki page which has recently been published for details on how to do this.
Let me know if you have any questions or issues.
Thanks,
Greg

NO 12:06 AM Software Development: Configuring the QUP pins: Hello,
My carrier board uses several QUP pins for I2C, UART, and SPI. How do I configure them? I prefer a device-tree solution over a userspace solution. Nathan Olson

NO 06:14 PM Software Development: Long build times: Hello,
I am extending the BSP with my own layer. It seems like whenever I make a change, a lot of unrelated files get recompiled (for example cameradlkm-1.0.qcom-r0, qcom-displaydlkm-git-r0, qcom-pal-git-r0, qcacld-wlan-git-r0, ...). ... Nathan Olson

WE 09:39 PM PCB Development: RE: Auto start: When talking about input power to the SOM that would be the 3V7-BAT rail.
There would be a delay between power being applied (on 3V7-BAT) and when the SOM would be monitoring the POW-BTNn but we haven't quantified this yet. We will se... William Evans
NO 09:14 PM PCB Development: RE: Auto start: Thanks!
Does power have to be high for a certain amount of time before the power-on pulse? If so, which rail and for how long?
Or can POW_BTNn be held low at startup, and released after 400ms? Nathan Olson
WE 07:30 PM PCB Development: RE: Auto start: The only "automatic" power on we have implemented so far is software control from an Arduino.
There are two main stipulations on the POW-BTNn:
# The power on pulse must be greater than 400ms.
# A power button press of 10s is a syste... William Evans
NO 03:15 PM PCB Development: Auto start: I'm using DC power and I'd like to auto-start the SOM when power is applied. What are the requirements for the signal on POW_BTNn?
Is there an example auto-start circuit I can copy? Nathan Olson
