- MW 07:53 AM Software Development: RE: Bare-metal interrupt handling working only in debugger
- Hi Alex,
Glad you solved your issue, sorry we didn't provide much help. We don't have a lot of folks trying to do Bare-Metal (and we don't do it often either).
-Mike - AL 06:22 AM Software Development: RE: Bare-metal interrupt handling working only in debugger
- No, that was obviously not the reason. The unhosted and hosted linker scripts do link against different libraries but that only seems matters for stdio. I was able to solve the problem by rewritting everything from scratch. The way I was...

- AL 03:50 PM 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 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 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.

- MH 05:20 PM PCB Development: RE: SoM pinout verification
- Thanks Adam. I'd been floating through the wiki and referencing the design guide heavily as well.
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 Software Development: RE: Ethernet Error When Upgrading to Linux 3.16.
- So I believe I solved my own problem. I compiled the kernel and then just dropped it into my sd card. When
I updated the kernel, something broke between the kernel and the device tree blob.
After the kernel compiles, the correct dt...

- Thank you for the info - we will correct the details.
Your assumption is correct. Additional design guidelines can be found on the MitySOM-5CSx Wiki:

With lo... - Parsing the datasheet prior to establishing a carrier board design, I observed the following flaw:
The table on pg 18 of the SoM datasheet available on the wiki (dated 19 November 2014) has pin 215 listed twice and omits pin 217.

- 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.

- Hi Ian,
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.
Here is a link the the 5CSX gitweb pa... - IR 11:04 AM Software Development: RE: Created SD card for the MitySom-5CSX development board not booting correctly
- Hi Dan,
No changes were made to an example project located in altera/14.0/embedded/examples/hardware/cv_soc_devkit_ghrd
If that is the problem is it possible to get a copy of the preloader and uboot binaries provided on the SD car... - DV 10:02 AM Software Development: RE: Created SD card for the MitySom-5CSX development board not booting correctly
- Hi Ian,
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 am using the MitysSOM-5CSX Altera Cyclone V development board booting from SD card. I have built the kernel, file system, u-boot and the preloader using the instructions on the WiKi. https://support.criticallink.com/redmine/projec... - All,
We just started a new project running on uC/OS-II. We selected MitySOM-5CSx Development Kit but most documents and project files are targeted Linux OS. Do you have any uC/OS-II base project we can use to configure and connect to ...

- Hi Malcom.
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.
The missing pin assignments will work (they are the HPS fixed pin assignments, and the fitter... - I've just started to evaluate the MitySOM-5CSX board and the first thing I did was install VirtualBox and the supplied Xubuntu image.
