I'm evaluating the Demo version of the ARM7 tools from Keil and notice a lot of unusual quirkiness when dealing with the Flash erase procedure called out in Philips' IAP section. Many times I've had to power down the eval MCB2100 board, constantly re-enter Debug mode, do the hokey-pokey, etc. to re-establish the code and get it to run. On one occasion, I had put into the Memory Window address 0xFFFFF030 (or any other address from the Vectored Interrupt Controller (VIC)) and my target just froze up. Anyone else experiencing strange stuff with this eval board and ARM7 tools? Thanks.
We have not such problems. So you must do something different? Are you using ULINK or just the Philips LPC2000 Flash Utility?
I'm using ULINK.
Are you using DK-ARM V1.3. Do you have any problem when you are using the BLINKY sample projects under \...\Boards\Keil\MCB2100?
I'm using the EVAL software for the ARM. The problem occurs when erasing and writing to Flash using Philip's procedure for IAP. Sometimes the code works okay, and then, NOT! This is beyond the scope of the Blinky program, which works okay.
Is it the CODE that does not work or the Flash Download process? Do you select the Flash algorithm as described under: http://www.keil.com/support/docs/2747.htm What version are you exactly using (Help About dialog). There are some core restrictions in the ARM JTAG interface. Basically you cannot use the IDLE instruction in a program that you want to test. See: http://www.keil.com/support/docs/2752.htm
I know about the issues you raised. The flash download process works okay and the code works. But like I said, I press the run button and sometimes the target (LED's lite) runs okay and sometimes the target does nothing at all. I set break points and it appear to go into the ether during the flash erase/programming stuff in the IAP.
How do I check the version? I see: SARM.DLL V1.16 DARMP.DLL V1.02 UL2ARM.DLL V1.02a TARMP.DLL V1.02 Not sure where to find the DK-ARM 1.xx version. All I know, it is the Eval version. I'm hesistant to purchase the real stuff until I see stability in what I'm discussing.
The problem that you are describing might be in your user application. You are currently using DK-ARM 1.2a. You may update to the current Eval version (download from: http://www.keil.com/demo/eval/arm.htm). Once you still encounter problems, please send your project files to: support.intl@keil.com. Include in this message a description of the problem and how it can be duplicated.
Well, I downloaded the links you gave me and am now running the newest stuff. I just downloaded my code and all seemed okay - at first. First try, so good. Then I stop the target from running, pressed reset, and pressed run again. Nothing happened on the target. Did this several times and it's hit/miss for the target to run. Something is strange. Thanks for the help. -Jim
Where can I "zip up" and email my code to?

Hi Jim, what type of LPC device you are using and what version has your bootloader ? Andreas
I using the Keil MCB2100 demo PCB. How do I find out which version of bootload. I'm using Keil's ULINK and DKARM Ver 1.3 (just updated).
Do not worry about the BOOTLOADER VERSION. It is not important.
