02:27 AM Software Development: RE: GP0[4] state on boot for L138F: ??How quickly do you need it to be low? You might put an external pull down on your board.??
Pretty much instantly... Mostafa Afgani

07:46 PM Software Development: RE: GP0[4] state on boot for L138F: How quickly do you need it to be low? You might put an external pull down on your board.
You could disable the pu... Michael Williamson
05:11 PM Software Development: RE: GP0[4] state on boot for L138F: 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

02:05 PM Software Development: RE: UPP problem: Problem was caused by cache incoherency. Use of BCACHE_inv() fixed it. stephan berner

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... Michael Williamson
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.... Benedikt K.

02:51 PM Software Development: UPP problem: hi,
I am having problems reading data from the FPGA to memory. I set up the UPP interface
using channel A from t... stephan berner

10:07 AM FPGA Development: RE: Mity L138F FPGA -> OMAP interrupt lines: Thanks Mike,
I have found the pin mapping for INT0 and INT1 I couldn't find the mapping for the Non Maskable Inte... Christopher Brunson
09:48 AM FPGA Development: RE: Mity L138F FPGA -> OMAP interrupt lines: 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.
From the MityL138.ucf... Christopher Brunson

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... Michael Williamson
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 ... Mary Frantz

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... Michael Williamson
01:20 PM Software Development: Adding SPI flash: We have a SPI serial flash device on our board, an M25PE80. It is connected to SPI1 with SPI1_CS1.
I created a ba... Mary Frantz

01:46 PM Software Development: RE: DSP HelloWorld Message Queue Buffer Length: Thanks for the clarification on the message handler code, and the message structure recommendation.
It definitely w... Doug Browning
11:01 AM Software Development: RE: DSP HelloWorld Message Queue Buffer Length: Doug,
As far as I understand the anLength is really the length of the buffer passed between the DSP and ARM and is... Jonathan Cormier
10:01 AM Software Development: DSP HelloWorld Message Queue Buffer Length: I'm modifying the DSP HelloWorld example code from the Wiki site to transfer data types other than strings (see SW Fo... Doug Browning
