OÇ 09:57 AM Software Development: RE: Changing UART1 to UART2 in Linux Kernel

Just noticed I left the @bootargs@ as @ttyS1@.
Changing that to @ttyS2@ solved that issue.
Sorry, I wasn't expecting such a simple solution. Okan Çalış

Hi,
We've been working on a MityDsp-L138F board, and I can boot to Linux with NFS, with the following environment variables: Okan Çalış

Hi,
I have a custom board with
1) MityDspl-138F module (with FPGA)
2) No Ethernet port
3) UART,USB,SD CARD interface
4) We are using ADC5560 and DAC5672, reference is taken from Analog Expansion Board.
ADC and DAC both operat... Vivek Ponnani

It doesn't look like we ever created that guide. I'd recommend looking at the provided source files as examples.

You'd want to extract the MDK filesystem, update the files and then generate the jffs2 image file. NOTE: We also generate a new tarball which we can archive o... Jonathan Cormier

I apologize for the awkward subject; it was meant to be _"Interrupts Between Linux and DSP without BIOS"_, but it looks like I can't modify it. Okan Çalış

OÇ 10:52 AM Software Development: Interrupts Between Linux and DSP without BIOS

Hi,
I've been working on a MityDsp-L138F with Linux Ångström.
I'm able to use the 128-KB shared RAM for inter-processor communication between the two cores, with ARM running Linux and DSP running baremetal. I want to send interrupt... Okan Çalış
