3 Replies and 1410 Views Linux USB Support  1410  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...

1 Replies and 1139 Views Is it okay to run module on one 3.3V supply?  1139  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.

0 Replies and 1423 Views 24-bit TFT panel support  1423  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!

2 Replies and 1562 Views NAND recovery of bad blocks  1562  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...

2 Replies and 1233 Views Questions about kit  1233  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!

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, ...

2 Replies and 1255 Views LITEKIT rev-5 changes to sheet-7 (LCD)  1255  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

2 Replies and 1271 Views WEIM buffer control signals  1271  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.

6 Replies and 1287 Views PMIC_PWRRDY signal in schematic  1287  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...

2 Replies and 1348 Views Question about DDR signal routing  1348  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...

1 Replies and 1273 Views Windows CE BSP boot parameter string for MX31 LoCE  1273  1 Started by  TimJohns 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. I beli...

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 ...
