Mass Storage not seen if QNAP Qfinder Pro installed
Hello! Problem: installing QNAP Qfinder Pro prevents VS1005's external mass storage mode from appearing in Windows 7/10 Our customer has been advised to contact QNAP. But I thought it would be good to look at both ends of the USB cable, so-to-speak - the error message seems very low in the USB stack...

Re: Command line for prommer
Panu, thank you for your reply. I copied eeprom_i.map from the VSOS_355g_IntFlash folder (image and map files are here) to the VSIDE\bin folder. Same result. After more troubleshooting, I moved my .bat script in to the VSOS_355g_IntFlash folder and everything worked. So, you pointed me in the right ...

Re: Command line for prommer
Hi Panu, Thank you for your reply. I see now that vs3emu first needs to know flash type, and from there will look for and load eeprom_i.img (we also call it "kernel.img"). Progress, but not there yet. Below, it hangs after it warns of "Can't open map file "eeprom_i.map" for reading", and "Can't open...

Re: Command line for prommer
Hello All, Based on my searches, this thread appears to be the most applicable to what I am attempting. Goal: use a Windows batch script (.bat) to load kernel image in to a blank VS1005g during factory programming. Problem: vs3emu appears to start well, but then hangs. Note: I am not responsible for...

Re: VS1005 RTC Frequency tolerance
Hello Pasi, If you have a ±10ppm 12.288MHz oscillator, that's also the accuracy of the samplerate. There's nothing inside vs1005 that would inherently lose clocks That is what I suspected; thank you for confirming. If you can use IOVDD (i.e. the oscillator works with 1.8V), you don't need to switch ...

Re: VS1005 RTC Frequency tolerance
Hello Hannu and Panu, I'm glad we are not making a tarriffe clock - way over my head. :) I've been thinking about this issue backwards. We need very accurate audio clock, not ultra accurate file timestamp. (Duh, David! :roll: ) Does a ±10ppm 12.288MHz XO linearly result in a ±10ppm 48kHz sample rate...

Re: VS1005 RTC Frequency tolerance
Hello Hannu,
Your other ideas are great food for thought. We will review.
Many thanks!
David

Re: VS1005 RTC Frequency tolerance
Hello Panu, A new, related question. We need to consider a more accurate RTC clock. I'm wondering if it is possible to switch between two hardware 32.768kHz clocks (one is low accuracy, low power; other is high accuracy, high power) depending on whether the product is turned Off and running from lim...

Re: VS1005 RTC Frequency tolerance
Thank you Panu.
I was thinking the same, but had to ask to be sure I wasn't overlooking something.
Thanks!

VS1005 RTC Frequency tolerance
Hello! In the VS1005 datasheet, page 10, Oscillator Specification table, it lists the RTC Frequency Tolerance as "±100ppm". Questions: Is this ±100ppm the range in which the VS1005 will work with a supplied clock (crystal, oscillator)? (i.e., if the supplied 32.768kHz clock is beyond ±100ppm, VS1005...
