Hi Martin,
I thought you might be interested to know that I successfully ran the sample
program for the STM32L100C by following the instructions in the txt file from
the mseuniverse/samples/embedded/arm folder. It makes a very neat dev system!
I have also used mseide to compile, load and debug programs for an STM32F446
after changing the cross compiler for the M4 and modifying the project options
accordingly.
However, there is one odd thing which I hope you can help with. After building
the program it takes three sequences of target->continue before the program
successfully loads and runs. Specifically, the following is observed:-
(target->continue)

If I send the commands too quickly in succession gdb can get into a state where
a hardware reset is the only way to resume communication.
I wonder whether in general it is a timing issue eg. the write commands issued
to the stlink interface are sent too soon after the erase command (a 16k sector
erase takes 250->500 ms to execute), and then the debugger is getting out of
step.
any suggestions?
Geoffrey
