Keil a mess?

Hello!

I've been using Keil IDE for 8051 since years and it always worked fine. Now I need to work with ARM processor. Since I'm new to it, I wanted to start with the examples. I got the MCB2300 board v4.0 with uLink 2 and, of course, the appropriate Keil ARM IDE with RV.

1. In all the documentation it tells about the JTAG jumper to be set for uLink - but there is no JTAG jumper

2. When I open the example project "blinky", the target is set to LPC2378, though the MCB2300 has LPC2368. The abstract.txt says, there is a target called "mcb2300 flash", but it's actually named "lpc2378 flash".

3. In the target settings, it already selected ULINK debugger, which is set to 1MHz speed, though the online step-by-step guide says it should be set to 200kHz

4. Compiling the project works fine, but going to debug reports error "memory mismatch, address: 0x0, value: 0x0, expected: 0x18" - this looks like there was no code. Is it required to create a hex file and if so, why is this not activated in the target options? I thought these are ready-to-run projects.

5. After activating "Create hex file", it still shows the error, but enters debug mode and the disassembly windows shows more than zeros

6. The code is running instantly, at least the JTAG interface says so. But there is no LED bar or character display on the LCD. The little beeper produces low, high frequency noise.
Looking into the code (as far as I understand the ARM assembler) tells me, it is not correct. Resetting the target to 0 and going stepwise lets the debugger jump to address 0xfffffff3 after a few steps. So the debugger does not really work. If I let the the code run after reset and stop it, it halts at 0x0000000C, going in a loop to 0x00000014. Not really a working code...

7. Opening example projects with abstract.txt in it gives error "abstract.txt contains a invalid path". Huh? Since when can a text file contain a path?

8. At least, example project EasyWeb compiles and uploads to the MCU. But then it says "Can't stop the ARM device - check JTAG cable". Hilarious! There is a hardware debug tool with a reset line and it can't stop the controller!
Even I manually reset the whole board by unplugging the USB cable and inserting it again, the flash uploader gives the same error. Sure, it is possible that the cable is broken, but board and uLink are quite new and the cable has only beed unplugged a several times.

Now I wonder how this can be possible. I mean, it can't be the way to read hundreds of pages and books just to be able to setup Keil! Why must every tiny piece of software have thousands of settings?
An ARM controller might be more complex than a 8051, but from the IDE it is still the same. Setup, project, compilation, debug.

This is a hardware/software package that costs some hundred or even some thousand Euros. I simply expect it to work!
I mean, what else can occur if not even small example projects work?

(By the way, selecting a different country still shows the american flag on the preview)

  • I'm running a bit older version of the tools - I don't much like upgrading when there is no need.

    Seems like you are right - Keil has been a bit lazy.

    For MCB2300 board:
    Blinky,RTX_Blinky,RTX_Traffic seems to have Simulator + Flash

    For MCB2100 board:
    Bliny,BlinkyCAN,BlinkyIRQ has Simulator + Flash + RAM
    RTX_Blinky: Simulator + Flash

    For MCB2400 board:
    Blinky has Simulator + Flash + Ext SDRAM + Ext NOR Flash

    Seems like Keil has been slowing down a bit. I can't see any real reason for the big lack of RAM targets for newer boards. It isn't completely obvious how to set up one, without having an example to look at.
