SN 05:48 AM Software Development: RE: Simple Code/Doc for FPGA toggle of GPIO from DSP

Thank you, you where spot, it solved the issue with only having one pin high at a time.
The following works
mpGpio->SetPinValue(0,0,1); //pin7
mpGpio->SetPinValue(0,1,1); //pin15
if i use
mpGpio->WritePins(0,0xFFFF,1); //al... stefan nielsen

Also, you should not be calling the destructor. This line is not OK: Michael Williamson

The driver could be rewritten to contain a shadow mask of the desired output register, but that is not the current implementation.

MW 08:28 AM Software Development: RE: Simple Code/Doc for FPGA toggle of GPIO from DSP

The code for the DSP GPIO control does a read modify write. It Reads the input state of the entire bank, masks the value you are trying to change into the register, and writes the register back out.
If, in your VHDL, you do not conne... Michael Williamson

Not sure what you mean with input ?,
both are mapped in the VHDL code as output. and set as output with SetPinDirection()
I can set both pin high, only not at the same time. stefan nielsen

Do you have the inputs of the GPIO core for offsets 0 and 1 connected in you FPGA design?

Hi
If i want to toggle both pin 7 and pin 15 at the same time i have an issue (both work independently). Pin 7 goes high, but as soon an i write to pin 15 it goes low again. I tried with mpGpio->WritePins(0,0x3,1)/mpGpio->WritePins(0,... stefan nielsen

SK 08:29 AM Software Development: Interrupt source code for DSP

Hi All,
I try to figure out how to serve an interrupt in the DSP code and how to register an ISR for a FPGA interrupt.
How can I register an interrupt system in the DSP code (interrupt from FPGA --> execute ISR)? Could anyone provide... Stefan Krassin

FA 07:08 PM FPGA Development: RE: Programming the FPGA

Hi
What was the solution to the last problem (add source error)? I get the same warning when trying to add pwm.ngc etc into a lx45 project.
thanks, Flemming Flemming Abrahamsen

SN 06:28 AM Software Development: Simple Code/Doc for FPGA toggle of GPIO from DSP

Hi im trying to toggle a pin in the FPGA(busy/awake LED would do for now) from the DSP. Is there a doc(howto) describing the order of configuration/initialization and usage?.
Been looking at files from MDK_2014-01-13\sw\DSP\lib\core a... stefan nielsen

OM 06:27 AM Software Development: RE: DSP/BIOS issue MityDSP-L138

Thank Alex for your answer.
I think a problem was in incorrect PINMUX for UART-1.
My design works fine for UART-0 and UART-2.
Best regards,

Oleh,
Can you please share some more details about this issue if it is still occurring?
It looks to me like Uboot is interpreting the file as text and trying to execute the commands.
Presumably the DSP has not taken control of t... Alexander Block
