Serial port driver/timing in windows CE 1778 3

Logic
The serial port not buffering any out going chars. Somebody(Logic or MS) is blocking my threads when I write to the port. I have put together a test app that if the serial port driver was interrupt driven and has a buffer should generate a pulsetrain with a period of 10mS - 11mS. It does not, I see the Writefile blocking until char is sent. I need to know why and how to fix this! My Windows image has all of latest drivers in it. Here is test my code:

non-functioning pmic when switching to lolo version 2.4.0 1710 1
Started by Deleted User
Has anyone noticed that the pmic no longer functions when switching from lolo version 2.3.5p2 to 2.4.0
We are running lolo version 2.3.5p2 and the PMIC is functional. The result from the function pmic_get_revision function is: rev1=3, rev2=3, icid=2, finid=0.
However, switching into lolo version 2.4.0 makes the pmic non-functional. The result of the pmic_get_revision function is: rev1=3, rev2=4, icid=4, finid=3. Upon further investigation, we've discovered that the icid needs be 2 in order fo...

Use of oprofile and gprof 2007 2
Started by Deleted User
Hello,
I've successfully built and booted Linux 2.6.19.2 following the instructions by DrOctavius and others. I am also able to run my application.
Now I'd like to gather some profiling information on my application; I built it with the -pg option and ran it on the board. After processing the gmon.out with gprof on the host I get correct call graph information but the times for all functions are reported to be 0.00. This is despite running the application for several minutes.
I also checked ...

Anybody using Compact Flash on Linux? 1648 0
Started by Deleted User
I am using Poky linux for "imx31litekit", and it does not seem to detect CF cards. LoLo is accessing the cards perfectly.
The kernel is 2.6.19.2 and apparently has the right config options:
CONFIG_PCCARD=y
CONFIG_PCMCIA_DEBUG=y
CONFIG_PCMCIA=y
CONFIG_PCMCIA_LOAD_CIS=y
CONFIG_PCMCIA_PROBE=y
CONFIG_PCMCIA_MX31ADS=y
(Serial) ATA is not enabled though:
Serial ATA (prod) and Parallel ATA (experimental) drivers
CONFIG_ATA is not set

Hi, I have a MX27 Lite Kit and I cannot get USB OTG to work in peripheral mode. We are not required to work in host mode.
So far when I connect the Lite Kit to my Linux FC5 laptop, the PC does not detect it.
Can someone take a look at my config below to see if I am missing something
Also the Lite Kit uses the SMSC USB3311 transceriver chip. Does anyone have the programming manual I only have the Data Brief. I am not sure how different it is from the Philips 1504 chip, which the MX27ADS board...

NAND boot 1683 0
Started by durian
Hi, we have LoLo running from NOR flash and we can have it copy a Linux kernel stored in flash to DRAM and boot there. But we want to delete the NOR flash device and use the NAND instead. Does anyone know about getting NoLo and having it load LoLo, which in turn then loads a Linux image from NAND
Does any know how to get a NoLo binary for a MX27 LiteKit board
Any help would be much appreciated...

LogicLoader script to collect user input 1616 0
Started by MarkH
I am using LogicLoader (Lolo) version 2.4.0.
I have searched the documentation, and have not found anywhere where it shows how to do the following:
I would like to be able to present a short menu of choices to the user, and have the user
input the selection. For example:
1) Run 'bootme'
2) Run 'exec' string
3) Boot image from NAND
4) Return to Lolo shell
Enter choice:
I would not expect the user to have to enter 'setvar selection 1'.
Any one have any ideas
Thank you.
