Another possibility is that IOVDD is configured to 1.8V (GPIO0_7 being low during reset) and external connected devices using 3.3V drive current through the protection diodes which pulls the voltage up to 2.4-2.5V.

Either way, the problem should be located and fixed.

Those high-speed DAC/ADC are technology for graphics card / video applications VLSI Solution was once involved with.

Currently VLSI Solution is more concentrated on audio.

I have two ideas to try to divide and conquer the issue. 1. Can you try 1.9V-2.0V CVDD? However, you already use lower than max clock, so this shouldn't change the situation. 2. Encode with the UART output enabled and don't read the data through SCI to see if the encoding still crashes. If a crash h...

Hi, it seems the libdev1000.a hasn't been updated in VSIDE for a while.

A workaround: make a lib/ subdirectory under the Player/ directory in the solution and copy the attached file there as libdev1000.a .

Can you send a small example file?

The most usual mistakes is a wrong byte order, or the storage not being able to save data quickly enough.

When waiting for data from the SDI FIFO, vs1163 tries to keep the audio FIFO relatively empty. Also, in vs1163 you can read the SDI and audio FIFO fill states using the parametric_x structure. (vs1063 datasheet 11.10: Write 0xc0df to SCI_WRAMADDR, read SCI_WRAM to get sdiFree, read SCI_WRAM again to...

You need to prevent boot by keeping GPIO0 low while you power up the module. You can then reprogram by using pcmodflash.exe .

It looks like the C preprocessor cannot create a temporary file in the directory.

It may be a permissions issue. Also check that you have decompressed the package first and not trying to compile inside the .zip package.

When using vs1063 standalone player without boot SPI: 1.Release AUDIO_RESET 2.Wait for DREQ to rise (you need the controller to read DREQ) or wait the appropriate time. 3.Upload the SCI-controlled player code from player.plg using SCI writes. See VS1063 Standalone Player/Recorder - VSIDE solution an...

Which value do you get when AUX is connected to GND? If you don't have anything connected to a pin, it probably biases to the reference voltage, which is why you get the same value for the reference voltage and the other input. And like Panu asks, what are you measuring for IOVDD and AVDD voltages w...
