- AL 03:50 PM MitySOM-5CSX Altera Cyclone V Software Development: RE: Bare-metal interrupt handling working only in debugger
- I am now thinking that I might have to use the unhosted version of the linker script (even though it worked just fine for compiling programs without interrupt handlers).
Might be that the Sourcery compiler does something 'weird' with th... - AL 02:36 PM MitySOM-5CSX Altera Cyclone V Software Development: RE: Bare-metal interrupt handling working only in debugger
- Hi Mike,
That address is indeed the base of the interrupt table. I have been using it without any problem with other programs, which run just fine and which were compiled using the same linker script (which always inserts a vector tab... - MW 11:20 AM MitySOM-5CSX Altera Cyclone V Software Development: RE: Bare-metal interrupt handling working only in debugger
- I personally haven't tried to do this before, but isn't address 0x30000000 the base of your interrupt vector table? Is that the actual runtime entry point (a jump instruction to the CRT) or is that an address for a reset interrupt? Can...
- Hello,
I am using the MitySOM Dev Kit and I want to use interrupts in a bare-metal
application. To that effect I wrote a 'small' program where I enable the private
timer (and the interrupt bit as well) and wrote an IRQ handler.

I have updated the programming Wiki (https://support.criticallink.com/redmine/projects/arm9-platforms/wiki/DSP_Quick_Start) to include how to store your DSP.out file to the SPI NOR Flash memory and how to boot the DSP from that ... - OM 09:17 AM MityDSP-L138 (ARM9 Based Platforms) Software Development: RE: DSP core starting
- Alex,
At present the size .out a file for our application makes about 1.5 megabytes.
Thanks - JC 08:38 AM MityDSP-L138 (ARM9 Based Platforms) Software Development: RE: DSP core starting

How large is your DSP image? This will determine if it can fit in NOR or if it needs to be placed in NAND. NOR is preferable as it isn't affected by bit flips. - OM 01:39 AM MityDSP-L138 (ARM9 Based Platforms) Software Development: RE: DSP core starting
- Alex,
Yes, I am looking for DSP only device (without ARM and linux). I have already wrote and debugged (by JTAG) fine working DSP core application for DSP/BIOS. So, I need load this one to non-volatile memory, prefer NAND (or elsewhere)...

- Oleh,
I am working on adding some documentation to our DSP programming Wiki.
However in the meantime can you confirm if you are looking to use the ARM core (and Linux) in addition to the DSP or are you just trying to treat the modu... - OM 10:21 AM MityDSP-L138 (ARM9 Based Platforms) Software Development: RE: DSP core starting
- Thanks for your prompt reply.
I want, that at power up on board the code (.out file) for the DSP-core was started (if I correctly understand "U-Boot command> bootdsp c0700000" demands participation of the user).

- Oleh,
I'm having a hard time understanding what you are asking for. Are you trying to load the DSP program on boot in u-boot or from Linux? - Hi,
I use CCS 6.x, DSP/BIOS 5.42.x, USB560 and MityDSp-L138F.
What it is necessary to make, that at power up of board MityDSP-L138F the program for DSP core was started in automatic mode?
Best regards,

Follow up on this comment, there are definitely other aspects of the table in the SoM datasheet indicated that are not in line with the... - JL 03:22 PM MitySOM-5CSX Altera Cyclone V Software Development: RE: Ethernet Error When Upgrading to Linux 3.16.

I updated the kernel, something broke between the kernel and the device tree blob.
After the kernel compiles, the correct dt...

Your assumption is correct. Additional design guidelines can be found on the MitySOM-5CSx Wiki:

- After successfully building my development system with Yocto, I find that the ethernet and GPIO no longer work
as can be seen in the boot sequence. Building a 3.12 system works fine. Any idea what this could be?

- I am using the provided VM. I only work on the firmware but I will get our hardware engineer to generate the handover files required. Hopefully that will solve my issue.
Thanks for your help.

Critical Link has a project made specifically for our development kit, it can be downloaded from our git site or if you are using our provided VM it should be under /home/user/projects.

I noticed 2 things when looking through the logs, it looks like the ethernet MAC can't find the phy and the kernel panics are coming from the USB driver.
Did you change any of the PIN muxing in qsys or is this from the base... - Hi,

I will check on the memory init files issue. I seem to recall that those can be ignored, but I don't remember why off-hand.

What version of the kernel are you running? Can you provide us the output to the command 'uname -a'? Also what 335x module model number and serial number do you have (the bad one and one of the "good" ones)?
