- SM 09:44 PM Software Development: RE: LCD Framebuffer Problem
- The P/N of the Dev Kit for L138-FI-236-RL is 80-000382 and the P/N of LCD is 80-000536.
- SM 09:40 PM Software Development: RE: LCD Framebuffer Problem
- Hi, Mike
I am using with Dev Kit for L138-FI-236-RL(80-000382) and 4.3In WQVGA LCD(80-000536).
I had to set the LCD Panel to NEC NL4827HC19-05B in the u-boot.
Can you explain in detail for eabling the backlight/LCD??
And, I wou... - MW 07:10 AM Software Development: RE: LCD Framebuffer Problem
- Hello,
You may need to enable the backlight / LCD with the fpga_lcdctlr driver.
There should be a sysfs entry for the backlight with controls for enabling the LCD (powering it on).
I don't have hardware at the moment, when someo... - SM 04:40 AM Software Development: RE: LCD Framebuffer Problem
- After rebuiling the kernel (kernelversion 3.2.0) with gcc version 4.5.4, I had to re-download the kenel.
I made the bin file of FPGA(XC6SLX45) based on the contents of the sites below.

- JC 08:42 AM Software Development: RE: LCD Framebuffer Problem
- What kernel are you using? Which defconfig? The lcd configuration is done in the file arch/arm/mach-davinci/baseboard-industrialio.c function baseboard_setup_lcd(). You may want to place some print statements in there to make sure the ...

- Hi,
I am being tested with Dev Kit for L138-FI-236-RL(MityDSP-L138F) and 4.3In WQVGA LCD.
The version of the L138-FI-236-RL is expected to be C.("14-08-06 C" on the sticker on the back of the board is shown.)
I tried to follow the...

- BD 04:45 PM Software Development: RE: OMAP L138 Cross-Compiling on Ubuntu 14.04 LTS
- Ben,
We are currently working on a unified VM release for our MitySOM-335x and MityDSP-L138 product lines (using a toolchain and filesystem that is Yocto compatible).
I expect that we'll have it released in 2-4 weeks.

- MJ 08:57 AM Software Development: RE: MityDSP-L138F - External SPI access from "Industrial IO Development Kit"
- That's great. We're using the 80-000268RI-2B so should be able to use those SPI1 pins.
Thanks for clarifying that.
- MW 08:01 AM Software Development: RE: MityDSP-L138F - External SPI access from "Industrial IO Development Kit"
- Hi Mat,
If you are using a board with a revision 1E or higher (see the "Industrial IO Revision Information":https://support.criticallink.com/redmine/projects/indio/wiki/Industrial_IO_Revision_Information), then you can use the J700 pi... - Hi
We're developing ARM software using ThreadX on the MityDSP-L138F (i.e. with FPGA), which resides on the "Industrial IO Development Kit".
We want to interface from the ARM to several off-board SPI devices but looking at the pin assig...

- Thank you Jonathan. If you can find a Ubuntu 14.04 ova file with all the tools configured, that would be great!
- JC 11:50 AM Software Development: RE: OMAP L138 Cross-Compiling on Ubuntu 14.04 LTS
- The standard MDK has been working for me. The following instructions should work for ubuntu 14.04, will see if I can get someone to run through them and verify. https://support.criticallink.com/redmine/projects/arm9-platforms/wiki/Linux...
- The following MityDSP link hints that Critical Link has a cross-compiling development environment for the OMAP L138 on Ubuntu 14.04 LTS, 64-bit:

- GG 09:40 AM Software Development: RE: NAND Flash garbage collector and performance issues
- Hi Fred,
We've run into issues here with system boot times slowing down after extended use. This does not sound exactly like what you're experiencing, but perhaps the cause and fix we found might be useful or relevant to your issue. ... - JC 09:15 AM Software Development: RE: NAND Flash garbage collector and performance issues
