SPI as master

Dear VLSI team, I compile the kernell 3.2 (with VSIDE 2.33) with the maximum debug capabilities. My program compile well but the linker complain about the missing _DevHwSpiCreate. I read the forum and I feel the usage of this function was only use with device driver development. Did I have to use an...

Re: USB unknow

I got exactly the same issue on my own board. I try to modify the scsci.c as you mentioned to add some debug capabilities whiteout success. I got an error during linking with the new VSOS kernell.

Do you have resolve your trouble, if yes how? By putting the PCB back in the hoven?

Dear Panu, My screenshot where the internal flash is mentioned is when I started from the VSIDE and clicking on the yellow play button named RUN. But If I close VSIDE, open a serial spy (putty) and reboot the device I got no message on my putty console. After a check with the oscillo no change on th...

Re: Evalboard schematic understanding S7 function

Dear Panu,
Thank you for your quick response and best wishes for 2015 year for you and your company.
Concerning your answer, could you say if GPIO0_7 is pull-up and I try to program the internal firmware with the standard cable with 3.3V interface if this operation could damage the VS1005G Rx/Tx pin?

Dear VLSI team, I try to understand the behavior of the VS1005G evaluation board when I keep S7 BOOT down when performing a reset. The U8 outputs seems to be connected only to the LED D21 and to the debug connector X2. I didn't see any interaction with VS105G input. I try to use the text search insi...
