Linux USB Support 1583 3
Started by Deleted User
Hello folks,
did anyone get the USB ports up&running using Linux
I tried, but failed.
The problems:
a) usb is disabled after applying the linux-2.6.16-mx31-lite1.patch (it adds a skeleton usb_lite.c file with just enough to compile)
b) after enabeling the USB-code for the ADS board again my system says
initializing FSL-SOC USB Controller
usbh1_init&58; grab H1 pins
USB_CLK=49410000, should be 60MHz
fsl-ehci fsl-ehci&46;0&58; init fsl-ehci&46;0 fail, -19
usbh1_uninit&58;
c) to solve...

Is it okay to run module on one 3.3V supply? 1311 1
Started by OradFarez
Hello. Is it okay to use just one 3.3V supply I would imagine that 3.3V on the battery input plus the 3.3V "legacy" input connected together should work okay. The voltage would go through the 20 milliohm resistor to get to VIN. Would that be okay or is there a better way Do I need to populate the charging circuit in order to increase my options
I'm planning on using a supercap for the 3.3V_uP_BATT so it's connection is separate. Thank you for your help.

hi,
i would like to know if it is possible to replace the logicloader with a custom bootloader (eboot, for testing purposes) using the jtag-port
is there any software to burn the bootloader image into flash over jtag (the image is in *.bin format)
Thanks, Andy

24-bit TFT panel support 1657 0
Started by Gadeberg
Hello, does anybody have experience in driving a (dumb) 24-bit TFT panels with the i.MX31 Supposedly it should be able to output 3x8-bit (RGB separately), and it would then need some external HW to collect the 3x8-bit to 1x24-bit to be sent on to the display.
Any knowledge in this respect would be useful!

NAND recovery of bad blocks 1757 2
Started by randyc
When I first got my litekit, it never complained about bad blocks in the Nand area.
Now, every time I use it I see:
yaffs: 68 blocks are marked by manufacturer as bad
and
NAND device: Manufacturer ID: 0x20, Chip ID: 0x76 (ST Micro NAND 64MiB 3,3V 8-bit)
Scanning device for bad blocks
Bad eraseblock 5 at 0x00014000
Bad eraseblock 7 at 0x0001c000
Bad eraseblock 9 at 0x00024000
and so on, until I presume all 68 blocks are listed. Is there some way to recover/reset this spac...

Questions about kit 1409 2
Started by OradFarez
Hello. I imagine anyone who has purchased a kit/module can answer this for me.
- Does the MIMX31CSOM module come with the i.MX31 or i.MX31L chip I really want to have access to the 3D core for my purposes.
- If I buy just the module, do I still have access to all the resources and downloads membership provides or is that only for people who buy the full kit
Thank you!

rube linux questions using litekit 1489 0
Started by randyc
In hoping to solve my kernel issues, I'd like to use the SD or Compact Flash cards to hold the rootfs of Linux.
Unfortunately, I am having three issues that a linux amateur like me can't figure out.
one - how do I get the litekit to see the SD card I preformatted the card using a different linux box and put an ext3 file system on there. Is that the right thing to do Is there some driver I should turn on when I compile the kernel
two - same thing but compact flash. Not sure what to do, ...

LITEKIT rev-5 changes to sheet-7 (LCD) 1407 2
Started by steve
I've been running through the LITEKIT rev-5 changes to check effects on our design at the same time nearly ready to start interfacing a different LCD panel (simlilar VGA-TFT). I see the new 22ohm R arrays on signals between the buffers and panel.
Were these mainly for signal rolloff, improved EMI, etc., or was there another goal I'll be using a standard 3.3v panel, so not sure of the need. For rolloff of hi-speed stuff, I would normally use a 10ohm.
Thanks for any tips - Steve

WEIM buffer control signals 1422 2
Started by Deleted User
Hi all,
the i.MX31 SOM is equipped with 3 buffers Philips 74ALVC164245. Their control signals are driven by 1.8V-powered logic but datasheet says:
"Control inputs voltage range from 2.7 V to 5.5 V"
so it seems the voltage swing is not compatible. Am I missing something
Thanks in advance.

PMIC_PWRRDY signal in schematic 1444 6
Started by gtridilbert
The i.MX31 SOM schematic (shown as "9/1/2006" on the downloads page, but indicating "August 1, 2005" in the date field of the schematic) has an oddity concerning the signal PMIC_PWRRDY.
On Sheet 12 of 14 of the schematic, PMIC_PWRRDY is mapped to GPIO3_0 of the i.MX31.
However, Section 4.5.1 of Freescale's "MCIMX31 and MCIMX31L Applications Processors Reference Manual (Rev 2.3 1/2007)" indicates that GPIO1_5 is the Power Ready input.
Is Freescale's Reference Manu...

Question about DDR signal routing 1541 2
Started by OradFarez
Now that new schematics and gerber files have been posted, I noticed that the major change was to the DDR SDRAM signal interface. I was wondering if this huge change really helped signal integrity alot or was the best result from using production memory over the pre-production memory you were using before
The reason I ask is that the IMXLITE kit is great for prototyping, but I have to design my own board for production. Any chance you have links to good DDR RAM layout guidelines I cannot f...

Windows CE BSP boot parameter string for MX31 LoCE 1455 1

I’m trying to boot Windows CE 5.0 using the LoCE BSP, from LogicLoader 2.3.1-IMX31_10 0001 on the MCIMX31LITEKIT, and I would like to know what boot parameter string to use to enable debug output on the UART to the DB-9 serial port connector, and KITL on Ethernet.
This is a headless system with no display.
I looked in the LoCE BSP User’s Manual and Quickstart Guide, as well as the LITEKIT User’s Manual and Quickstart Guide and the LogicLoader User’s Manual, but still need some details.

LCD panels > VGA res 1497 0
Started by steve
Has LPD (or anyone else) tried any testing on small panels larger than VGA res We are looking at a 4.3" 800x480 TFT (similar tft timing as the smaller Sharp VGA panels), but I see a few performance issues with VGA panels on the iMX site. We are waiting on the next iMX hardware, and are using the PXA Zoom for development until then. The iMX spec covers > 800x480, but just wondering if that will be a performance problem in the BSP or on the SOM
Anyone have a data or experience for that ...
