Problems flashing LPC2148 with ARM-USB-OCD and LPCUSB stack

Development Boards MicroMod
1

I can flash simple programs with my ARM-USB-OCD, but when I try to flash a simple HID application with the LPCUSB stack it fails. If I use the Philips ISP program and flashes the .hex-file the HID application works. It also worked when I compiled it to be run with the debugger in RAM.

When I run debug after a ARM-USB-OCD flash it goes to the “UNDEF”-handler right after initialization.

Also if I first flash it with the ISP tool, then flashes it with a simple program with the ARM-USB-OCD (which works), then flashes the HID application with the ARM-USB-OCD again, the HID application also works. But if I then change a parameter en the HID application (i.e. VendorId in the descriptors), and re-flash with ARM-USB-OCD it fails again.

Any suggestions?

Hello,

which version of the OpenOCD did you use? Does your HID application make use of interrupts?

Please send a log (run with -d -l ) to Dominic Rath gmx de.

If your code is larger than 4K the you must erase more than sector 0 before programming.

For 8K

erase first bank only:

flash erase 0 0 0

#CHANGE TO

flash erase 0 0 1

Probably using the Philips ISP loader with a small program erases the remaing sectors but only writes to the first sector, thus preparing flash for programming your larger program.

Thanks Magnus, it worked!

Darn !

I’ve been fighting with my JTAG pod for a few hours with the same problem.

In my defense, the OpenOCD Quick Reference Card

http://www.fh-augsburg.de/~hhoegl/proj/ … ickref.pdf

states:

"flash erase Erase

blocks first to last of flash bank."

which is WRONG !

The official command from here

http://openfacts.berlios.de/index-en.ph … D_commands

has

"flash erase

Erase sectors at bank , starting at sector up to and including . Sector numbering starts at 0. Depending on the flash type, erasing might require the protection to be disabled first (e.g. Intel Advanced Bootblock flash using the CFI driver)."

Uggghhh.

I’ll email the author and ask him to correct the sheet before it catches anyone else.
