- Hello everyone,
We are using the debugger Blackhawk XDS560v2-USB and try to test it to debug the Helloworld program provided here.
Previoously we have run the program directly under linux and in works fine.
However, now I am getti...

- Hi,
I'm trying to figure out how best to gain access to one of the two SPI ports on the L138. I have an Industrial I/O board with an L138F module and we want to interface it with some external eval board hardware that has SPI slave c...

- Never mind... I was able to successfully use the bin file out of build_dvi_revc_lx45 to validate with the Impact tool. Thanks

- Hi,
I'm using MDK_2014-01-03 and wanted to just validate the FPGA programming mechanisms outlined in the wiki. Is there a generic .bin file available to test with or do I have to build one from the examples?

- Tom,
For following the Wiki, the "Release 2014.01" MDK is the best choice right now. The Wiki documentation has not been updated to match the newest MDK releases (e.g. Release 2017.08 - BETA).
After you work through some examples... - Hi,
Just getting started here with a MityDSP L138F dev system. The USB stick had release 2011-03-31. Which is the best MDK release to use that the examples listed on the wiki coincide with? It appears Alpha release 2016.01 is more too...

- Tom,
You can find the pin-out of the JTAG adapter board in the datasheet for the board (http://www.criticallink.com/wp-content/uploads/80-000286_L138_Debug_Adapter.pdf).
Please let us know if you need anything else,
Alex - Hi,
Can someone point me to the docs that outline the pin assignments for the 2 user connectors on the emulator adapter board -- Critical Link (CL) part number 80-000286.
Thanks, Tom - BW 05:11 PM MitySOM-5CSX Altera Cyclone V Software Development: RE: spi mode error
- This solved the error but there is no change to the spi mode.
- MW 01:56 PM MitySOM-5CSX Altera Cyclone V Software Development: RE: spi mode error
- I think the SPI_IOC_WR_MODE is looking for the argument to be an address pointer (char*) pointing to the SPI_MODE_1 value.
Can you try: - BW 01:34 PM MitySOM-5CSX Altera Cyclone V Software Development: RE: spi mode error
- Yes I can send and receive using : ret = ioctl(fd, SPI_IOC_MESSAGE(1), &tr);
but only in spi mode 0x0. If I try and set the spi mode using the command above I get the pavort error. - MW 01:02 PM MitySOM-5CSX Altera Cyclone V Software Development: RE: spi mode error
- Is your file descriptor, fd, valid?
- BW 01:00 PM MitySOM-5CSX Altera Cyclone V Software Development: RE: spi mode error
- I have not been able to get this to work. Does anyone have any idea why this is happening?
Thanks,

* Q: void* DspAddr: What is the physical address of DSP that I should be reading from ARM?
* A: This depends on how you structure your application. One example would be having the DSP allocate a chunk of heap data and filli... - OÇ 07:06 AM MityDSP-L138 (ARM9 Based Platforms) Software Development: RE: Inter-Processor Communication between ARM & DSP
- Hi Greg,
Thanks for your reply.
I examined @dspapp.cpp@ in the MDK, and noticed @ReadMemory()@ is a simplified version of the @PROC_read()@ function of DspLink. About the function arguments:
*@void* DspAddr@:* What is the physical...

- Hi Okan,
Regarding your need for the ARM to read memory written by the DSP there is a function call ReadMemory() in the ARM tcDspApp class. If you setup a structure where the DSP uses DspLink to communicate an address the ARM is to r... - OÇ 06:21 AM MityDSP-L138 (ARM9 Based Platforms) Software Development: RE: Inter-Processor Communication between ARM & DSP
- Hello again,
I consulted to my colleague. It turns out, we don't insist on using SysLink instead of DspLink. But we definitely need a shared memory mechanism where the DSP writes some data to the memory, send an interrupt to the ARM, an... - OÇ 05:43 AM MityDSP-L138 (ARM9 Based Platforms) Software Development: RE: Inter-Processor Communication between ARM & DSP
- Hi Greg,
The communication method Critical Link provides is great; the code was easy to follow and I understood most of it.
The problem is that it supports only message buffers, but we may need to use "shared memory" communications...

As a qualification I want to mention that DspLink is the communications and control method Critical Link supports and recommends using at this point. Our MDK provides wrappers around DspLink for loading the DSP via the ARM a... - OÇ 05:39 AM MityDSP-L138 (ARM9 Based Platforms) Software Development: RE: Inter-Processor Communication between ARM & DSP

Thanks for your response. My first question was really confusing me, so thanks for the explanation.
Considering neither Critical Link nor TI technically supports DspLink anymore (you provide your own functions instead, and the...

Here is some feedback regarding your questions:

I've been working on a MityDsp L138F board with Linux Ångström run by the ARM core. I'm expected to learn and implement various possible IPC methods to make the cores communicate with each other.

I have follow you guidance. it improve the LCD touchsceen response. However, it's still hard to be used.
Do you have recommendation on capacitive touchscreen that supported by Critical link?
