Formatting an SD card to smaller size in Windows

Hi all! VS1010 can use SPI NAND flash as read only data storage if you make a disk image that fits inside the Nand, and then have the VS1010 copy the image into the Nand. The first step is to get your hands on an SD card that has suitable size. And in case you don't happen to have a small SD card ly...

Re: MP3 File Playing Noise

Is this problem only in 1 board, or several? Maybe the flash is corrupted somehow...?

Re: Upgrade VSOS from 3.50 to 3.55 question

Hmmm, strange. :geek:

Did you update just the kernel from 3.53 to 3.54 or have you also updated/changed the PLAYFILES.DL3 program and/or any other files in the SYS folder of the flash?

Re: audio compressor/limiter

Ok, understand, you want soft knee limiter. I'll ask Henrik when he gets back to the office next week.

Re: audio compressor/limiter

Hi!

Can you explain what kind of compressor/limiter you need. What are the parameter values? What is the application of the compressor/limiter? Can you give a web link to a device that basically does what you need?

Re: MP3 encoding data are missing

Hello! I don't think that VS1063 guarantees that the is pushed to the buffer exactly one frame at a time. But I suppose that is not the problem? Could it be that you simply don't read the data fast enough? Can you give a specific example of what goes wrong, e.g. when you run this... wordsn = Vs1063a...

Re: audio compressor/limiter

Hi! Of course, we support ReplayGain. We also have compressor/limiter, but that is completely unrelated to the matter. Please google ReplayGain, and see the wikipedia page https://en.wikipedia.org/wiki/ReplayGain -Panu Hmm, mmm, ReplayGain might not be in VS1010 ROM. I could check how to load it int...

Re: SPI & SD works but no sound is to hear.

Hmm, if you play from the command line, try to use TAB instead of ENTER to terminate the PLAY command. Does it play then?

Re: RDS Radio compile problem with asm files

The mem_desc file has no relevance.

There may be a new prototype for WriteIMem added in some header file recently. Try changing your code to:

WriteIMem((void*)(0x20+INTV_FM), ReadIMem((u_int16) (&FmIntVector)));
