- Certainly... The PCB number is "120540". I've no boards plugged in at all - just the L138 module and the baseboard. There's only a single wire pushed into the connector which is connected to a voltmeter.
I'll try another one.....

Do you have an expansion board plugged in right now? Can you disconnect it if you do?
It's possible that the outputs might not match the inputs if there is an external driver or short that is stronger than the driver in th... - CO 08:29 AM MityDSP-L138 (ARM9 Based Platforms) Software Development: RE: Simple GPIO toggle
- GPIO0/15 is the opposite which is rather odd. It starts out as 0, whereas GPIO0/7 starts out as 1:
root@mityomapl138:/sys/class/gpio# cat gpio15/value
0
root@mityomapl138:/sys/class/gpio# echo "out" > gpio15/direction

When I cat from /sys/class/gpio7/value, it reads "1" all the time, no matter what I've previously written. I did think that I was reading from the wrong pin so I had checked that...

- Hi Conor,
I don't see anything wrong with your approach. You might check the value that the pin is reading back (e.g., cat /sys/class/gpio7/value). If the pin is stuck, it should right a "1" in all cases. If it is toggling, then per... - I see this has been asked before in various ways so sorry to ask again (I'm not getting it!).
I have pin 19 from J700 hooked up to a meter. The MityDSP docs say this is GPIO, bank 0 offset 7.
So I should be able to toggle the pin b...

- Like to seek your help on an uPP related question. I plan to burst out I and Q data from memory using the two uPP channels to the FPGA. In fact, I plan to drain most of the 256MB RAM using multiple DMA calls (if required). I see from ...

Did you get through this, do you still need assistance?

- So anyway, the mod-fastcgi.so should not require you to rebuild the kernel. You should be able to download it, "configure" it, and install it on your platform filesystem.

- Greg,
Thanks for answer.
By the way, do you have a dummy FPGA load (in .bin format) that output "known fake data" on uPP?
It can be very very very useful.
Thanks!

Glad to hear that fixed your problem!
In regards to your follow up question, yes, you will most likely need to invalidate the cache on your receive buffer each time before passing it into the DspUpp receive function in ... - MW 12:54 PM MitySOM-335x (ARM Cortex-A8 Based Products) Software Development: RE: mod_fastcgi.so

You was right on and you make my day!
Now, I have another question regarding the cache. I used the uPP in DLP mode for uPP driver integration. However, it is a temporary solution because our FPGA is not yet ready. When our FP... - GG 02:24 PM MityDSP-L138 (ARM9 Based Platforms) Software Development: RE: Problem with uPP in DLB

We have not done any work with running the system in digital loopback mode. The fact that you are getting a response back and not just hanging on the receive mailbox is a good sign. The pinmuxing should not matter as dig... - I am trying to use uPP in DLP mode with an MityDSP1810F board but my rx buffer is still empty after a "ransaction.
