Thank for your reply Mike.
Is it possible to write an image FPGA through СОМ1 on MityDSP? Whether it is possible to make it under Windows?

Hi,
I have board L138-FI-236-RL.
Developed in Xilinx ISE the design fine works on FPGA at use ISE iMPACT.
Please, tell a step-by-step how to create an image for FPGA and how to provide working of the design at power off/power on.

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

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 MityDSP-L138 (ARM9 Based Platforms) 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

SN 08:04 AM MityDSP-L138 (ARM9 Based Platforms) Software Development: RE: Simple Code/Doc for FPGA toggle of GPIO from DSP

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

Hi Jack,
Is your software designed to be executed in linux?
If so then you will need to have linux execute it on startup and not uBoot. Here is a brief description of what needs to be done: https://support.criticallink.com/redmine/... Daniel Vincelette

Hi Paul,
loopback devices are not built into the provided kernel. You will need to either build it in or add it as a module to your kernel.
Once loopback support is added to your kernel, you should be able mount it with following: Daniel Vincelette

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.

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.
