- SW 10:49 PM MityDSP-L138 (ARM9 Based Platforms) Software Development: RE: OMAP GPIO
- Hi Mike,
It turns out I didn't enable the Industrial Board I/O option in the kernel. After I enabled it (and enabled MUX debug output to verify the GPIO pins are configured correctly), I can toggle the GPIO pins.
Thanks,

- Hi Simon,
I don't see anything wrong here, but you might want to ensure that the pin-mux configuration is setup for this particular GPIO. I thought that the stock ARM linux kernel provided by Critical Link did this for you, but if yo... - Hi,
I'm having trouble accessing the OMAP GPIO pins as detailed in the "MityARM-1810 PROFIBUS Dev Kit" documentation from the DSP.
I am assuming the OMAP_GP0_xx pins means bank 0, and xx means the offset. I'm using the core library... - (Posted on behalf of a customer):
We need to boot the DSP fast (up and running code in less than 2 secs. ) and then continue with ARM/Linux boot?

- Hi.
At the moment, your observation is correct, the current bootloader does not support loading code directly to anywhere other than DDR2 from FLASH with the hex images provided. Initialized DATA (via cinit) should be OK. The issu... - (posted on behalf of a customer using MityDSP-Pro)
I have so far only loaded & run via CCSv5, but soon I will want to run via boot from a hex file stored in FLASH. However, I see an ominous note under "IRAM" on pg 28 of your Day-1 PM... - (posted on behalf of a customer who is using the MityDSP-Pro)
I've been trying to put an interrupt service routine (ISR) and the data it touches into L1P & L1D on the c6455 (MityDSP-Pro). Using L2 for code & data works fine, but I ca...

- Tim,
Thanks for the help. I see the source in the code tree and also see why I couldn't see it in menuconfig. My problem now is when I try to compile. I think I am missing a step in my setup. I get this error:

The FTDI serial drivers should be in the kernel source tree (as of kernel v 2.6.31)
Its the "USB FTDI Single Port Serial Driver"

I want to access a device across the host USB that uses a FTDI chip to transmit serial data across the usb. When I plug the usb device into the MityDSP the usb device is recognized correctly, but the FTDI usb to serial driver is...

- Also, as a followup question, the StarterWare examples are setting up the system for the evmOMAPL138. For instance, the UARTecho example tries to configure UART2 while the MityDSP is setup for UART1. Are there examples setup like the s...

For the starterware non-os method, I have built some of the starterware examples using code composer. I have converted those to bin files with the out2rprc executable.

- At the moment, we don't provide customized packages. The mityomapl138 location was generated during the bitbake build as part of the configuration scripts. We didn't catch it when we built the filesystem up.

- Mike,
Thank you very much. I understand. - MW 04:51 PM MityDSP-L138 (ARM9 Based Platforms) Software Development: RE: about boot
- The EXT_BOOT# signal drives a small mux circuit on the SOM that changes the boot strap pull-up/pull-down options on the OMAP-L138 such that it will use UART0 instead of SPI1_CS0 as the primary boot device. If you need details about this...

- The bare board PCB for the two variants of the SOM are identical, the only difference is the BOM used for assembly. Pins 170 and 172 are still routed to the balls on the FPGA (E7/E8). However, I'm fairly certain that these pins are not...

- I wonder how the boot mode switch from SPI1 to UART1 using EXT_BOOT# signal? Thank very much.

We have done a design using the MityDSP-L138F SOM. I tried avoiding using the pins on the FPGA that are not connected in the larger variant, but I was not succesfull, meaning I accidently used two of t...

First, the reason you're getting the "-sh: ./hello.o: Permission denied" error is because the file you are trying to execute does not have execute permissions set.
