[beagleboard] Re: PocketBeagle USB1 Question

Your first connection does not work, because you are trying to power the USB1 from the USB_VIN, but since the is no power going into USB_VIN on USB-0, there is no power to come out USB-1. This only works when the board is powered from USB-0 The schematic does not tell you, but USB_VIN, USB0_VIN a

I'm fairly confident the answer to my question about whether the 8250 driver implements "partial 485 capability", (allowing Python or a C#/.net application to manually control the RTS line for a given UART via the driver) is NO. But the OMAP driver DOES appear to allow this. When I toggle the

I, too, am wondering about the best way to provide power to the board and to a device connected to USB1 as host. Here is how I learned to hook up a micro-b breakout to USB1 and also how I intend to provide power to the board. The problem is that there is no measured voltage at USB1:

It can be trusted. Does not matter whether one pushes RST (reset) button or plugs in power as long as SD card is in first and then SD button is held down and only after this power it up. Make sure to use BBBL images (not BBB like I at first did ;-)) and be patient when botting, i.e. it will show

The one I was thinking of was the Freescale/NXP Kenitis K66 series. 180 MHz, ARM M4F (I guess not 200 MHz, but close.) Available on a maker board as the Teensy 3.6 https://www.sparkfun.com/products/14057 Ti, NXP, Stm, may also have fast M4F, but it would take some digging. Microchip has P

Yes, it is possible. Also, probably extremely painful learning experience. There are ARM processors that are designed to run with OS. They start with the letter A. The processor in the Beaglebone is an A-8. There are ARM processors that are designed to run without OS. They start with the letter

I could yes, but I read somewhere (can't remember where exactly, but it was in some TI PowerPoint presentation that reading the eCAP register takes at least 4 cycles, which is not ideal for my purposes. In the meantime I found a way to use the BBB built in PWM as a CLK signal and it works now. C

Thanks, Graham. You are correct. I have already used these pins before, but for output purposes, so, I had no issues with that. But, since using as inputs, the switches are driving the pins and changing the SYSBOOT (aka LCDDATA) bus, which I had no idea that existed for my unfortunate surprise.
