Re: USB Mass Storage Device doesn't work.

Thanks a lot! Hmm, now that it boots, does the IOVDD rise to 3.3 volts?

Re: USB Mass Storage Device doesn't work.

Hmm. ok, understand. Like Henrik said, this was coded blind, we didn't have this flash IC at hand to test it.
Ok, please post all UART output from boot until the formatting fails. Maybe we can spot something in the output.

Re: USB Mass Storage Device doesn't work.

Hi! Any idea why i can't format the disk? Yes. SPI flash chips that don't have page write to RAM buffer are not very common and writing to them is painfully slow, so the kernel doesn't do it. The prommer has this option mainly to be able to write factory fixed firmware to the chip. It's ok for appli...

Re: USB Mass Storage Device doesn't work.

Hi! Ok, things are starting to make more sense step by step. Hmm.. does your IC have VS1005G or VS1005GF marking? The XCS is always low, which is fine i guess. You should definitely see proper XCS access cycles when the prommer tries to detect the flash. And pull-up on the XCS line is needed to atte...

Re: USB Mass Storage Device doesn't work.

This is asked a lot, and it's probably not applicable to your VS1005g version, but do you have FVDD (IOVDD2) connected to IOVDD? If you connect it now to VSPROM9, how often do you get a good connection, e.g. the board is detected correctly? When you connect VSPROM9, does it show manufacturer ID, dev...

Re: USB Mass Storage Device doesn't work.

Ok, thank you. Now, if it shows up as USB audio device, that means that it's running ROM code and it has not booted the OS. You must write the VSOS kernel to the flash. Please see the link that I gave you about flashing a new or bricked VS1005 board. This post in that thread: http://www.vsdsp-forum....

Re: USB Mass Storage Device doesn't work.

Hi! New PCBs are often tricky to get working in the start... but let's see. Which VS1005 version do you have? What is printed on the top of the IC? As you power up the IC, what is printed to the UART0 console? Please connect a terminal to it with 115200 bps baudrate. -Panu -- Flashing new or bricked...

Re: Block Move... with transparency?

Hi! No.. and I agree it's a major limitation of using the block move as a blitter engine :( Personally, I've been toying with the idea of making sprites as lists of rectangles, so there could be gaps, but it has obvious drawbacks. (drawbacks, lol..) I think the most efficient way would be to use the...

Re: VS1053 SS_REFERENCE_SEL creates audible pop

Hi!

There was a side effect of some internal function that it sets the reference to the default (low) value. Hmm, hang on for a day or two, we'll see what to do about it in this case.

Re: My first question

Hi, and welcome to the forum!

Have you taken a look at the VS1000 module? It allows you to store ogg sound files in the included SPI flash or on an SD card and play them using GPIO pin triggers or serial commands? It's one option on how to do it.
