2 Replies and 1236 Views Loading root image to NAND FLASH over UART?  1236  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 ...

1 Replies and 1278 Views Memory init for iMX31  1278  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

1 Replies and 1305 Views LTIB question  1305  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...

2 Replies and 1486 Views PMIC/SPI not working  1486  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...

0 Replies and 1329 Views Choosing the best Linux distribution  1329  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...

3 Replies and 1352 Views More information on LoLo please...  1352  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...

2 Replies and 1282 Views MPEG4 encoder under linux  1282  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

5 Replies and 1307 Views Board not booting up.  1307  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

1 Replies and 1260 Views JTAG recommendations for Linux and NOS  1260  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

1 Replies and 1305 Views TFT panel timing setup  1305  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

0 Replies and 1287 Views USB Host with Linux  1287  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
