Hi,

Where to install ARM Exception Handlers (i.MX27 Lite Kit) 1403 0
Started by Deleted User
Hi,
I want to provide my own Exception Handlers overriding the ones provided by LoLo. ARM documentation says High Exception Vectors are mapped to 0xFFFF0000. This location is however reserved for i.MX27 processor.
Where can I install my custom arm exception handlers. I would like to install ARM exceptions in VRAM not over-writing locations from 0xFFFFFF00 to 0xFFFFFFFF where I can install IRQ handlers.
Can some please provide me the info.
Thanks in Advance,
Rishi

How to connect to KEY_ROW2 using expansion breakout board? 1515 0
Started by nedkonz
We've got an i.MX27 LITEKIT and we're prototyping a product that needs a 4x4 keypad.
It's lucky that our keypad doesn't need to be any bigger, because the remaining row and column lines are being used for other purposes on the SOM.
I've managed to track down how to connect to all but one of the KEY_ROW0-3 and KEY_COL0-3 signals, using the expansion breakout board to get to these signals.
However, I can't figure out how to get to KEY_ROW2 using the expansion board. It doesn't seem to be avail...

Hi all,
The latest version of the Linux kernel is supporting the MX27 chip now. It's submitted by Pengutronix and Freescale MX27ADS is in the list of supported boards. I hope soon we can see MX27litekit is on the list as well.

Hi all,
Is there any progress on running Linux on the I.MX27 Litekit We have tried to use BSPs from both Timesys and Freescale MX27ADS but did get any success. Whenever we 'exec' the kernel image in the Logic Bootloader, the kernel stalls just after uncompressing.
Are there any patches or tricks we need to apply on the kernel Are there any successful cases by others We would be greatly appreciate any help.
