1 Replies and 1312 Views iMX31 Litekit runs at 400MHz or 532MHz?  1312  1 Started by  serkam Dear Sirs I read the PLL registers from iMX31 of my Litekit using a JTAG Debugger ( SEGGER JLINK ) and the values showed me that this iMX31 is running at 400MHz, instead 532MHz. Is that correct I mean, the iMX31 Litekit runs at 400MHz If so, why this frequency The Litekit can't reach 532MHz Thanks. Sergio Kamakura Warp Tecnologia Ind Com Ltda

(Topic has multiple pages1 2 3 4 )
Hi everyone, just wanted to let you know that I got a Linux installation ready which supports many (almost all) features of the LITEKIT. Here is the list of peripherals I've successfully tested simultaniously: * USB HS host * USB OTG host * IDE in UDMA mode * PCMCIA * Ethernet SMSC9117 * MMC In the first place, I followed the instructions from, but there was still some code missing here and there. I patched around for a couple of days an...

2 Replies and 1348 Views serial eeprom: how to erase it? URGENT!  1348  2 Started by  serkam I have a Litekit loaned from Future Electronics Brazil. This Litekit came with a script to boot Windows CE on power-on, probably done by a previous customer. I did try to erase the serial eeprom using: erase 0 128 /dev/serial_imx31_ff but the command didn't operate. I got an error: error: erase: erase failed ((0) start=0x0: len=0x80) and the Litekit continues to try to boot Windows CE. I did try also: erase 0 128 /dev/serial_eeprom as listed in the operating manual, but this device do...

0 Replies and 1327 Views Power Benchmarking?  1327  0 Started by  cmcp Hi! Is the LITEKIT SOM-LV a suitable platform for performing power benchmarking of the i.MX31 CPU What I would like to do is run various standalone benchmarks on a bare machine under a variety of conditions and be able to measure the current on each of the CPU's power rails (or, at least, be able to measure the CPU's total power draw) . I know there are current-sense resistors in the power paths from the LITEKIT to the SOM-LV. Is one of those paths dedicated solely to the CPU Regards. -...

6 Replies and 1290 Views PCMCIA Bus Timing Problem  1290  6 Started by  davek Has anyone experienced timing problems on the PCMCIA bus I'm using a Compact Flash ethernet card, and it seems that the output enable from the MX31 is turning off before the MX31 samples the data bus, due to delays in the buffering. Has anyone else seen this problem It seems to be violating the timing requirements of the MX31.
