Re: Migrating from XHRA to XU208

Hi. I've been using the XU208 using the XHRA migrating firmware for a number of years successfully but I now have a requirement to know the current sample rate of the stream. I see on the original XHRA data sheet that GPIO_3, GPIO_4 and GPIO_5 would toggle according to the active sample rate. I know...

XU208 Max Sample Rate

Okay this might have been discussed briefly in other topics in this forum but I'm getting nowhere trying to increase the max sampling frequency of my custom board using an XU208. I have modified the MAX FREQ define in customdefines.h and devicedefines.h to 384000 in the USB Audio 2.0 software but I ...

Re: Migrating from XHRA to XU208

** Update 2 **

Installed the XMOS evaluation drivers and I get streaming... yey!
But why does it not work on the Microsoft native audio class 2 drivers of which the XHRA worked?

Re: Migrating from XHRA to XU208

** Update ** Turns out that I had the 384K_EN tied high on my original circuit which is X0D06 pin on the XU208 used for boot configuration - need to be tied low for QSPI boot. Circuit now enumerates on PC as 'xCORE-AUDIO Hi-Res 2' but my new problem is it won't stream audio!!!! If I go into sound pr...

Re: Migrating from XHRA to XU208

No luck programming the spi flash out of circuit. The XU208 still does not enumerate? I just want to reiterate that my custom board closely resembles the circuit of the XK-USB-AUDIO-HPA board and has worked perfectly until I fitted the XU208, so I don't think PCB layout, USN traces or power will be ...

Re: Migrating from XHRA to XU208

I'm using the IS25LQ016B device. I've created a .bin file following the instructions on the first page of this topic and will use an external programmer to program the spi RAM and try that. I am a total novice to the xTIME environment so coding up a flashing led will take me some time to work out! I...

Re: Migrating from XHRA to XU208

I did what you said and that cleared all of the previous warning. I had a new set of warnings appear but I assume they are normal, I've attached them anyway.
I've flashed the device and still no enumeration :-S

Re: Migrating from XHRA to XU208

I'm a complete novice when it comes to xTIME so excuse the stupid questions. Okay so going back to building the software I get the warnings shown in the attached JPEG. I'm assuming this is not normal even though a binary file was created? Other compilers I use would not create a binary/hex file with...

Re: Migrating from XHRA to XU208

Hi, Sorry for the delay in getting back to you on this. I've kind of had progress in that I tried another one of my custom XU208 boards and that seemed to flash straight away. The only thing is I had some warnings appear at the start of the flash process... Warning: F03098 Factory image and boot loa...

Re: Migrating from XHRA to XU208

Power attached.
The reset (POR) is connected to another remote board and I use a PIC microcontroller to control it via an IO expander. This pin is internally tied up to 3v3.
