Re: USB communication fails on ESD test / USB response status == EPROTO (-71) in Wireshark/USBmon
still it is strange to me that not calling XUD_SetReady_OutPtr() brought exceptions error in the XUD_LLD_IoLoop but I havent enough experience of the USB protocol and I cannot provide usb traces to suggest improvement. Thanks for reading. Yes, that doesn't sound correct. If you have a small example...

Re: Technical Guide to C for xcore - new YouTube tutorial
BTW I'm not sure this is a new video, some old video seems to have made their way to the xmos YouTube channel of the last day or so, im not quite sure what's happened here (not my department ;))

Re: Technical Guide to C for xcore - new YouTube tutorial
I think the issue with understanding is that the hardware was designed to run the language (see early presentation: http://people.cs.bris.ac.uk/~dave/xarch2010.pdf) and so its very integral to the whole xmos story. lib_xcore is somewhat trying to provide a C compatible API like XC. So if you already...

Re: Create Xmos Resource Map File from within XTC command prompt
You're referring to the option to the compiler maybe?
Code: Select all

Re: XMOS schedule for xCORE-AI USB Audio apps
To add to Joe's reply, xcore.ai is a superset of xcore-200, it that in can use its internal PLL to generate master-clock frequencies. This is an additional feature, rather than a restriction. An up an coming release will include sync to external sources using this PLL, but this doesn't seem to be wh...

Re: XCC Compiler Bug - No Exit Condition in Assembly for uint8_t Array
I've raised the issue internally and it has been reproduced. Initial reports from our compiler team: It effects the XC compiler only and optimisation levels > 0 It doesn't effect the C compiler at any optimisation level The type of the array isn't significant but the type of the counter variable is....

Re: XCC Compiler Bug - No Exit Condition in Assembly for uint8_t Array
Use -save-temps to save intermediate files (i.e. .s files)
-fcomment-asm can also be handy
