- MW 01:01 PM Software Development: RE: Cannot run multiple times my ARM/DSP application
- Hello François,
On the DSP side, if you are using the tcIPCInbound class, are you calling the ReturnBuffer() method in your callback handler? You need to do this or else the underlying POOL objects used by the GetBuffer() calls are n... - MW 12:52 PM Software Development: RE: Non-FPGA module NAND Timings
- Hi,
Yes, currently the NAND timings are set up in the u-Boot code in line 290 of the file:
u-boot/board/davinci/mityomapl138/mityomapl138.c
The current linux kernel port for the MityDSP-L138 family of SOMs does not modify the NA...

I don't know if somebody has seen this kind of issue. I have a ARM/DSP application based on the "DSP HelloWorld". I added some message queues and tasks. The ARM/DSP application is messages intensive. After boot, everything is goin... - (Posted on behalf of a customer)
In the wiki it says that without a FPGA the NAND access changes: "... on the Industrial I/O host board, by adding additional wait states to the default NAND timings (contact critical link for details)....

Yes, I have only spotted that today, but when I changed the inputs to 0b10, with some difficulty since they are tiny pins, the unit still does not work. I have missed a few bits out but I suppose that is why we do dev boards.

- Hi Charlie,
I went back and reviewed your hardware design.
It looks like you have PS1 and PS0 floating on your design. This will result in the Serial Bus configuration to become "I2C Master Mode for EEPROM" and will set the person... - SP 09:53 AM Software Development: RE: Increasing CPU speed

Some parts of your answer were really helpful and gave me some hints such as I think I can proceed.
My hope was, that you could help me with a code snipped (or link) how you implemented the core voltage improvement, bec... - MW 08:12 AM Software Development: RE: Increasing CPU speed
- You have both the ARM+DSP running sysbios? Which do you intend to control the CPU speed (they are tied to the same clock)? I am assuming the ARM?
If you have reference code for the TI OMAP-L138 EVM: the key difference you'll need to... - Hello,
As mentioned in the title, we plan to increase the cpu speed from 300MHz (default) to 456MHz. In a Linux environment this isn't a problem because the command

Thanks for the suggestions.
1) The line you mention is the line I had to remark out to get the unit to run. I have now changed it as per your suggestion and linux now runs correctly, but still not the switch.

- OK Charlie,
Three things:
1) In the board file, I think you need to configure the emac_pdata->phy_id to "". This means that the kernel should assume the PHY is always connected (which it is).
2) Not sure how the strapping works... - CK 10:41 AM Software Development: RE: KSZ8995MA Ethernet Switch Support

I can't find what is causing these two error messages. Any help would be appreciated.

We've seen this issue before, but haven't been able to track it down yet. It seems to be benign, so I would not worry about it for now. I'll be sure to post any updates here if we find anything else out.

There is a newer image, but it simply has the newer MDK images and toolchains installed as well as support for the MityARM-335X (Cortex-A8 prod... - Hi Folks,
The Wiki says the current version of the VM appliance can be downloaded, but I can't find a download link. Does one exist?

Thanks, that did the job.
The bad news is that 3.2.0 does not have KS8995 support. It seems that this only starts in 3.3.0

Thank you for your assistance. I would like to look at the version 3.2, so if you could let me know how to access it I would be obliged.

I guess the first question is, "what do you want to do with the switch?". As I mentioned before, we have successfully implemented the KSZ8995 into at least one design here, and if you have all the ports mentioned above co... - CK 09:22 AM Software Development: RE: KSZ8995MA Ethernet Switch Support
