@poleguy UART is working now yay! Just realised that the Reset and Power Pins were high-low inverted grrrr...

@poleguy Thanks for reading my posts! :-) Here's the long story...
(1) Yep I wanted to get the PinePhone LTE Modem running with USB on NuttX. I built the USB EHCI Driver for PinePhone:
https://lupyuen.github.io/articles/usb3
(2) But the LTE Modem won't respond when I tried to enumerate the USB Devices. So I want to check over UART whether the LTE Modem is powered up and responding to simple AT Commands.
(3) Actually UART might be sufficient if we're building a simple Feature Phone with Phone Calls and Text Messaging only. (Which is my current objective)
(4) Genode OS managed to get the LTE Modem talking over UART. So I'm trying to reproduce their configuration:

(5) Right I'm not getting any meaningful output from UART. Thus the troubleshooting continues :-)

@lupyuen
So what's your take on this? It seems UART isn't supposed to be the interface used and the designers intend you to use USB. Why are you trying to use the UART with hardware flow control when it's not wired that way? Of course it won't work unless the bandwidth is trivially low and the system was designed to not block, etc. Does it also not work with hardware flow controll turned off? I'm not an expert, but do own a pinephone.
UART Hardware Flow Control is broken for #PinePhone 4G LTE Modem 🤔

If you find that you always need to add gluten, you can also get flour that has a high protein content naturally built into it called hard wheat flour. Then you wouldn't need to add the extra gluten.
It's often used for pizza dough but can also be used for bread.
Floofiest loaf yet ... 1️⃣ Add Vital Wheat Gluten 2️⃣ Double the yeast 3️⃣ Cover with warm towel when rising
