MW 11:02 AM Software Development: RE: Kernel loading module problems MityDSP and FPGA configuration
Did you also rebuild the FPGA drivers? They are not in-tree in the kernel git repository. They are located in the board support package in the MityDSP Developer's Kit.
Let's start with this:
On the build machine:

SB 10:40 AM Software Development: RE: Kernel loading module problems MityDSP and FPGA configuration
Dear Michael,
let me know if my way of working is right:
1) I wrote my own baseboard-industrialio.c file as reported in the firts post of this discussion.
2) I recompiled the kernel as reported in https://support.criticallink.com/re...

MW 07:30 AM Software Development: RE: Kernel loading module problems MityDSP and FPGA configuration
Hello,
We have many customers able to load and run modules with the MityDSP-L138, it's not obvious what the issue is here. I am suspicious that there may have been a problem with the filesystem installation / update (either the modul...

SB 04:00 AM Software Development: RE: Kernel loading module problems MityDSP and FPGA configuration
Dear all,
attached you can find a text (LinuxLoading.txt) file where I captured the entire boot together with the screenshot where "Failed" occurs (FailuresLoadingKernel.png).
I also run "uname -a" and the results are in the text fil...

AB 04:29 PM Software Development: RE: How to run bin application via u-boot?
Ahmed,
I believe Mike was suggesting that you build the application as a "release" version without any debugging and see what the resulting application file size is?
I.E. if it was 5MB in debug maybe it's 2MB in release, thus no ne...

MW 04:04 PM Software Development: RE: How to run bin application via u-boot?
Just to confirm, you have the compiler option "--symdebug:none" in your release compile and link options?

AS 03:51 PM Software Development: RE: How to run bin application via u-boot?
Hi Mike,
I have tried what you mentioned and it didn't work.
I'll wait your trial.
Thanks in advance.

MW 03:02 PM Software Development: RE: How to run bin application via u-boot?
I think you need to strip the .out file (make a release version that removes the debugging information).
If I get a second I will try it out.

MW 10:47 AM Software Development: RE: Kernel loading module problems MityDSP and FPGA configuration
Hi,
Can you please capture the entire boot up on the console to a text file and set it over?
Or at least run "uname -a" and report the results?

SB 10:38 AM Software Development: RE: Kernel loading module problems MityDSP and FPGA configuration
Dear Bob,
when I try to load the modules with "insmod fpga_ctrl.ko" I get an error with "Function non implemented" as explanation.
I also found on internet that the insmod error message is caused by either a kernel lacking module sup...

BD 09:30 AM Software Development: RE: Kernel loading module problems MityDSP and FPGA configuration
Hi Silvano,
Jon was referring to the kernel modules explicitly. The modules need to be installed in your target root filesystem (/lib/$kernelversion) after you copy over the kernel.
The page you reviewed, does mention this, but it'...
Bob Duke
SB 08:47 AM Software Development: RE: Kernel loading module problems MityDSP and FPGA configuration
I report before that I recompile the kernel every time I made a modificatuon on the baseboard file.
In fact the link you report me is cited by me in my first message.
Maybe there is something wrong in the file or in the compiling.
Cou...

JC 08:24 AM Software Development: RE: Kernel loading module problems MityDSP and FPGA configuration
Its hard to tell from those error messages whats going on but have you tried recompiling the kernel modules when you made changes to the kernel?

JC 09:53 AM Software Development: RE: Compiler does not run in VM
Also our vm does come with the toolchain installed. I'm unsure why you were unable to locate it.
Try looking in /usr/local/oecore-i686
The instructions seem to be missing that you need to run @. /usr/local/oecore-i686/environment-s...

MW 09:29 AM Software Development: RE: Compiler does not run in VM
Yes. You need to run the 32-bit version in the VM if your VM is a 32-bit architecture.
on your VM type "uname -a". It should tell you the version of the VM architecture.

AS 09:04 AM Software Development: How to run bin application via u-boot?
Hi everyone,i have MityARM1808F.
I could use "bootelf" command[ex: bootelf 0xc0700000] to run any app.out,but the size of .out format is usually large(in my case is about 5 Mega byte which is too large to be saved on SPI flash with FPGA...

AS 08:54 AM Software Development: RE: UPP ISR is not called
Finally i could solve this issue by adding the following code :
asm(" mrc p15, #0, r0, c1, c0, #0\n\t"
" orr r0, r0, #0x00002000\n\t"
" mcr p15, #0, r0, c1, c0, #0\n\t");
before calling BIOS_start function.

I assume you mean the EMIFA clock (to FPGA) not the EMIF clock (used for the DDR).

MW 11:44 AM PCB Development: RE: uPP Interface
I don't think that the UPP pins are pinmuxed (there is only one option if the UPP is used). See the MDK/sw/dsp/core/tcDspUpp.cpp for pinmux setting.

OM 09:16 AM PCB Development: RE: uPP Interface
Thanks Mike for reply.
The question will be, to what pins DSP connected pins FPGA? It needs to be known for purposes PINMUX.

MW 07:08 AM PCB Development: RE: uPP Interface
The UCF file in the board support package at MDK/fpga/vhdl/MityDSP_L138.ucf includes connection information between the UPP interface pins and the FPGA.

Hi John,
You are correct. We've pulled in this fix and it will get published in the next release for the MityDSP-L138 BSP.
Thanks for the bug report.

Michael Williamson
JC 01:54 PM Software Development: DspFpgaGpio.cpp: i f (Bank > mnNumBanks) return -1
FYI.
In tcDspFpgaGpio::ConfigurePin(unsigned int Bank, unsigned int Offset, etc.) and a few other fctns in DspFpgaGpio.cpp, there's a test for a valid value for the Bank arg and for the Offset arg, like:
