Hi Mike, thanks for the explanation. As we need this pin to be low on power-up, would the best place to set this be i... Mostafa Afgani
03:40 PM Software Development: RE: GP0[4] state on boot for L138F
Hi,
If you check the OMAP-L138 datasheet (it's a bit convolved) Table 2-29, the GP0[4] pin pullup state is defined...

10:19 AM Software Development: RE: USB Bug
There are several missing features in the 3.14 branch that I found when trying to move to it. I created a tag to mark... Jonathan Cormier
10:13 AM Software Development: RE: USB Bug
Note that we have seen a similar issue on the 335x. Could you checkout the following page and report back if the solu... Jonathan Cormier
10:11 AM Software Development: RE: USB Bug
It is from your git page - as far as I remember. Our software student tried to jump to 3.14 two month ago but it didn... Benedikt K.
09:39 AM Software Development: RE: USB Bug
Hello,
Are you using a 3.7 branch from our git site, or the mainline? I don't think we officially support 3.7. D...

09:37 AM Software Development: RE: USB Bug
Another thing: When I plug in the first usb device the number of usb interrupts in /proc/interrupts increases. When I... Benedikt K.
09:22 AM Software Development: USB Bug
Hej hej,
we have noticed a usb bug on the MityDSP and we are not sure why this happens.
We are using linux 3.7....

09:36 AM FPGA Development: Mity L138F FPGA -> OMAP interrupt lines
I was trying to use an FPGA interrrupt which should be serviced by the DSP core in the OMAP.
From the MityL138.ucf...

09:55 AM Software Development: RE: Adding SPI flash
The part works in SPI mode 0 or 3, but I tried all four modes (0 - 3). I also tried setting the fields .c2tdelay and... Mary Frantz
09:45 AM Software Development: RE: Adding SPI flash
Is the SPI mode field correct (polarity and phase, CPOL and CPHA is the part in SPI_MODE_0)?
You also look like y...

09:06 AM Software Development: RE: Adding SPI flash
I confirmed with a scope that the chip select was not active.
I added DA850_GPIO2_15 to the the array of gpios in ...

09:19 AM Software Development: RE: Adding SPI flash
It would not apply (different driver, different logic handling platform arguments). Michael Williamson
09:17 AM Software Development: RE: Adding SPI flash
Note that if you want to use the hardware designated chip select for that spibus instead of a gpio then the SPI_INTER... Jonathan Cormier

06:18 PM Software Development: RE: Adding SPI flash
Hi Mary,
Have you configured the pin-mux for the DA850_GPIO2_15, which would correspond to the chip select you are...
