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

08:33 AM Software Development: RE: How to probe the fpga_ctrl & fpga_gpio.ko module: Have you made any progress with this problem? Jonathan Cormier

11:31 AM Software Development: RE: How to probe the fpga_ctrl & fpga_gpio.ko module: yes,
echo "146" > /sys/class/gpio/export --> sh: write error: Invalid argument
it may be that fpga_gpio... HYUNG KI KIM

04:31 PM PCB Development: RE: Protecting MityDSP module during development: Hi Udi,
Yes the FPGA I/Os can be damaged by sinking too much current - powered or off. The I/Os have protection d... Adam Dziedzic
03:39 PM PCB Development: Protecting MityDSP module during development: We just fried a MityDSP L138F module, and I'm not sure why. I'm suspecting that the problem was that we had an ADC mo... Udi Fuchs
