In any case, it doesn't explain the hanging you mentioned. Did you
manage to get a debug log when it hanged?
There are a lot of variables here: OS, libusb version, adapter,
target. The following configuration seems to be very stable for me:
Ubuntu 10.04
Libusb 1.0.6 (in Ubuntu repo)
Jtagkey-Tiny, Olimex ARM-USB-OCD and Olimex ARM-USB-OCD-H
STM32F100 and STM32F103
If you or anyone can test configurations with only one or two
differences at a time it would be very helpful to locate the
problem(s).
I've done performance testing with the following openocd.cfg:
---
source [find interface/ftdi/jtagkey.cfg]
#source [find interface/jtagkey.cfg]
#source [find interface/ftdi/olimex-arm-usb-ocd-h.cfg]
#source [find interface/olimex-arm-usb-ocd-h.cfg]
#source [find interface/rlink.cfg]
source [find target/stm32f1x.cfg]
#source [find board/stm32f4discovery.cfg]
#source [find board/stm32vldiscovery.cfg]
