Loading root image to NAND FLASH over UART? 1403 2
Started by OradFarez
Hello. I'm sorry if this is a real "nubie" question, but I guess that is what I am.
Can someone give me complete instructions on how to load the root filesystem (busybox) onto the NAND flash on the litekit
Can I use the one made by the Freescale ltib package If not, can someone provide instructions
Hopefully, for each person who posts a question here, there are dozens who read the responses and learn from them, so I think this is a worthy topic.
Reviewing the other topics on ...

Memory init for iMX31 1424 1
Started by amiko
Hi All
Does someone has a full list of memory registers values which are known to be stable with the Lite-kit.
We plan to use the boot from nand so we skip the build-in boot loader and use for now JTAG in order to copy our bootloader into the DDR.
Right now , when we do it, the system is not stable and crashes from time to time.
When we boot from the LoLo and then load our code into memory via jtag the system is stable and linux is running.
any help or hint will be appreciated
Thanks

LTIB question 1450 1
Started by Deleted User
Hello,
I'm having a problem with a package I added to my LTIB projet for an iMX31 litekit eval card. I build the package with "./ltib -p mypackage"
What happens is that the package's makefile needs to compiles a tool that it uses to generate header files. Sadly, the invoked gcc is the one that is spoofed, i.e. the arm cross compiler. So the build fails, as the pentium cannot execute the tool.
what can I do to set the CC_FOR_BUILD environment variable to the host's gcc (compiles fo...

PMIC/SPI not working 1653 2
Started by lwalkera
I've been trying to figure out how to get the PMIC drivers to work so that I can get access to the touch screen ADC channels and RTC. Looking at the schematics I saw that the PMIC chip is on CSPI2, so I enabled the MX31 CSPI driver and the CSPI2 channel (adding any others causes the kernel to hang on boot).
The SPI master driver seems to load ok, but the probe for the device driver for the PMIC never gets called and when other modules try to use it, it ends up passing a null pointer for the *sp...

Choosing the best Linux distribution 1545 0
Started by OradFarez
I am just wondering which Linux distribution has the most features. There have been several releases of the ltib based Freescale version which leads me to believe it is quite complete when it comes to accessing important features (to me anyway) such as 3D, USB devices (wifi,hard drives,bluetooth), SD cards, PMIC features, etc...
I have been following the work that people have been doing to build a 2.6.19.2 version with a big patch that contains a lot of features, but just how much is there ver...

More information on LoLo please... 1523 3
Started by OradFarez
Hello. I have designed my own baseboard which will be incompatible with the baseboard expected by the LoLo software. For now, I believe it is okay until I start using different features (second SD card slot instead of CF, different GPIO usage, etc...). Eventually I want to overwrite LoLo in NOR flash with Redboot since it is open source and I can make any changes I want.
I have modified and built my own version of Redboot based on the one in the ltib freescale linux package, but I haven't be...

MPEG4 encoder under linux 1434 2
Started by Deleted User
Has anyone been able to compile the module
I am using zonque's (daniel) patch along with http://www.bitshrine.org/gpp/linux-2.6. ... rt-2.patch
For the last patch, i had to patch the main module file by hand. Oddly enough the top part wasnt patched, but the rest was.
The module itself compiles, but then later complains about undefined clk_* symbols.
I couldnt find what .c file has the functions for the mx3 platform.
regards,
Vinicius Kamakura

Hi all,

Board not booting up. 1452 5
Started by hrshk
hello everyone,
We trying to integrate i.MX31 SOM-LV with our own hardware module. The CPU module does not boot up and we are not getting any message on the serial console. Most of the signals like power and clock look to be fine.
Since we are not getting anyting on the serial console the problem seems to very basic. Can someone give us some pointers on what signals/pins to look at
Thanks,
Harish

JTAG recommendations for Linux and NOS 1402 1
Started by spannring
I'm about to start work on two different products. The first product will be rather simple and we've decided to go with NOS (no-operating system). The other is a more complex system with several custom peripherals. We're leaning toward Linux for the second product.
What would you recommend as a JTAG interface for doing Linux development (device drivers, etc) on the i.MX31 SOM-LV Is the BDI2000 a decent choice

TFT panel timing setup 1449 1
Started by steve
I'm adjusting the LCD timing params for a new TFT panel. I have HOR & VER timing dialed in pretty well (looks great), but cannot quite get the pixel clock width & period exactly where I want. I'm using the iMX DI & SDC registers in the 0x53fc0xx range. The LPD signal I want to tune is LCD_CLK: J1&91171&93, iMX31&91N21&93.
Can anyone give me a tip in the iMX register that defines the LCD pixel clock period and width
Thanks for any tips

USB Host with Linux 1483 0
Started by Deleted User
Hello Developers,
I connected the MX31Lite KIT host USB port to an unpowered hub.
The power LED's on the hub doesn't light up.
I checked the schematics and looks like the ISP1504 should enable power to the USB port if the driver works.
I also rebuilt the kernel with CONFIG_ISP1504_MXC=y with no improvements.
Anyone had sucess with USB HOST
Regards
Vasant
