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... Michael Williamson

03:28 PM Software Development: GP0[4] state on boot for L138F

Hi, we noticed that the power on state of GPIO_0_4 is that it is driven high. I am a little confused about this since... Mostafa Afgani

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... Michael Williamson

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.... Benedikt K.

Hi Chris,
The information you need is in Table 4 of the "Carrier Board Design Guide":http://www.criticallink.com/w... Michael Williamson

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.
