Re: Boot issue on custom board with tools 14.3.2

Thanks for the reply. Ok, another wrinkle, for the better. Using SM16: debugger no go as above, run no go (also tried adding xtag-divider in extra), flash ran 1 hour without completion (and no errors shown in verbose mode). SM8: debugger and flash good, have not tried run. Using my field firmware up...

Boot issue on custom board with tools 14.3.2

I am having some trouble with a custom board that is expandable with either 1 or 2 expansion boards. Using all XU216-512-TQ128-C20 parts. Main board has one tile with each expansion having 2 tiles in series (XL7->XL0). Connected from XL7 + XL0 from the main to each expansion to boot from SPI from ma...

Re: xflash problem cant find target XN

Removing --target-file and --spi-spec doesn't work either. target-xn-v0-5871c5f1: Error: F03000 Failed to open file: target-xn-v0-5871c5f1. I was able to generate a bin file and successfully use through the run / flash inside xTimeComposer. Put in my options in the correct fields and it generated th...

xflash problem cant find target XN

Using Community 14.3.0 on linux. Trying to generate a .bin from the .xe file.

Re: XCore 200 USB Port Usage

Thanks for the link to the speadsheet. I hadn't ran across that yet. I need to study all those pins and numbers is great detail, to verify my schematic... I assumed that the ports used by the USB phy when assigned to each tile, would be the same ports for either tile. So Port1E, etc. would be used f...

XCore 200 USB Port Usage

Searched, couldn't find another thread. Found different port usages (XU216-512-TQ128 datasheet): https://s23.postimg.org/t2xph9vlj/XMOS1.jpg From the USB Library v3.1.2 (these 1 bit ports are confusing to me): https://s28.postimg.org/43kxn3zvt/XMOS2.jpg I had wanted to use P1A0, until I found the ab...

Re: Reading rotary encoder (getting random values)

In my use, a simple bit test didn't work. The switches are noisy. You need to use a state machine to detect valid transitions between the two channels (and reset on errors) to detect CW and CCW rotations. I did not need to de-bounce, but I did limit to 10mS reads. I don't have XC code for this routi...

Minor Install bugs in xTimeComposer V13.2.3 Linux Version

Using latest Linux Ubuntu Wily (15.10), there are 2 very minor bugs you need to correct to get it installed and working using Version 13.2.3 and JAVA 1.8. XTAG2 is good. 1 - Newer JAVA versions changed output slightly. Installing OpenJDK Java 8, as now latest version in the distribution, the output ...

Re: New XMOS chips??!

My likes: External power again. No 1.8V rail for the USB part. TQ parts. My concerns: To use more than 2 tiles, must use 128+ pin parts. Rules me out. 128 pin part is too big. I noticed the speeds as listed: XL208Speed.PNG So you can no longer get 125Mhz per core with only 4 active cores (500 MHz gr...
