Re: VS1000 - Writing to NAND

The audio files can be read correctly. However, once the usb is disconnected and then reconnected the ending of some or all of the audio files will be missing Did you use the "remove hardware option" of windows before disconnecting or set windows to do_not _use_buffering (normally default at least ...

Re: VS1000 devBoard: external power to VCC connector allowed

Dear Panu, Thx for your information. My problem was that I already was on a business trip with that equipment when I realized this potential problem. Now that I'm back I instantly added a wire from C19 (UBUS+, regulator input) to a free pin of the pin header to connect external power, which seems to...

VS1000 devBoard: external power to VCC connector allowed?

Hello, is it ok to apply external power directly to the VCC/GND connectors of the VS1000 developer board for a stand alone demonstration?

Re: Instruction memory map utility

Hi Panu,

thx for providing these tools.

Kind Regards
Michael

Re: VS1000 devBoard, flashboot only after reset

Dear Panu, thanks for your extensive research regarding this issue. But your remark "VS1000 memory is not cleared at reset" lead me into the right direction. Of course when the internal ROM player was run once, several initializations are done. In case of the flash boot, I have to do the initializat...

VS1000 devBoard, flashboot only after reset

Hello, I uploaded my current project as the bootfile to the flash, as ususal using VS1000_B.RUN and nf_xyz.img, which worked fine up to now. Jumpers are set for nandlfash boot. But the current boot program doesn't start immediately on power-on. Instead, on power-on the default player from internal R...
