We want to use Dave4 to configure and program the Controller XMC4700. In our design we have a FPGA which will be connected with the demultiplexed or multiplexed external bus. So we have to configure this external bus (CS, Timing, multiplexed/demutliplexed, ...), but I can not find an APP (-> EBU) in the DAVE4. How does Dave4 Support this Settings?

Hi
I have installed dave 4 into two different pc running windows 7. In one it works. Into the other the compilation process fail with the following error message:
process_begin: CreateProcess(NULL, echo., ...) failed.

It seems to me that the problem is in the command @echo. that is automatically inserted into the various makefile.
On dave 3 in the same makefiles was inserted @echo ' '

Why on one windows 7 pc it works and not in the other? which settings have I to check?
Is it possible to modify a template so that the automatically generated makefile includes @echo ' ' instead of @echo. ?

Which version of Dave 4 have you installed ?
In latest version of Dave 4 the echo string is surrounded by single quotes:
e.g @echo 'Invoking: ARM-GCC Print Size'

I think this is another Problem and not an answer to my question. Does anybody know how Dave4 supports the Settings for the EBU?

We do not plan to develop an EBU APP, but we have in mind to develop an EBU CONFIG APP, which create an init function to initialize the EBU module and to operate it the XMC Lib can be used. Also for this APP is no firm plan yet.

Hi oreste,

we have the same problem for XMC4800 and it would be very nice if you could implement such an EBU CONFIG APP in the next time.

In the meantime, do you have an example how to initialize the EBU without an APP?

Hi oreste,
Do you have EBU CONFIG APP or EBU configuration example available? I have an application that have to use EBU for external SRAM and external Flash access.

Hi,

Have a look at the XMCLib distribution. In the example folder you will find an EBU example to interface a SDRAM device.
