I ended up with a whole pile of the Eli-Express cheap boards - the
first lot arrived with protection enabled in such a way that even
a genuine STLINK programmer couldn't unlock them. Complained to
the supplier so sent another batch - with the same problem. Ended
up having to build a special rig to unlock them with some help
from an ST app note.<br>
<br>
Glad to hear that GCC comes well regarded, sound like I will
pursue gcc-arm-none-eabi, and try it with Keil IDE. Also glad that
it's not me with concerns about ST Cube.<br>
<br>
Hopefully catch up on Monday, for the ARMstravoganza with Dave
Jagger.<br>
<br>

<div>I've done a few STM32 projects. I use gcc on Linux.
I did use the ST Cube thing to rough out the CDC class

<div>Most recently, I'm working on a system using an

full speed). It works fine. Still heaps of space. That
would not be possible using the standard ST HAL stuff.<br>

<div>Under Ubuntu 16.,04 you can get all you need by
getting the binutils and gcc packages for ARM.</div>

</div>
<div>That is unfortunately broken (some screwed up
libraries) under 18.04 and you'd do better with the
gcc-arm-embedded PPA</div>

<div>For debugging I use gdb with openocd (sometimes

<div>I have used many different debugger devices, but I
currently use an STLINK V2 most of the time. $2.
Can't go wrong.<br>

<br>
Does anyone have any experience with the various toolchains
out there <br>
for the STM32 ?<br>
<br>
Most of the stuff I do is bare-metal, but am definitely not a
fan of <br>
stm32cube, or Eclipse.<br>
<br>
Obvious choices seem to be Keil uVison; the limited code-size
trial IDE <br>
seems to be excellent. but looks like $$$$ is involved for the
<br>
professional unlimited versions. I understand that ARM bought
Keil a <br>
while ago, and that this product is their tool of choice.<br>
<br>
ARM do have a free toolchain gcc-arm-none-eabi (85MB)
available, which <br>
seems odd given the conflict of interest with Keil.<br>
<br>
openSTM32 (owned by ac6) have an open source 'System Workbench
for <br>
STM32' which seems bulky (!) at over 450MB.<br>
<br>
Finally, at least the older uVision toolchain appears to allow
GCC tools <br>
to be installed. Anyone used this combination, if there is no
code limit <br>
size on their debugger, this would be ideal.<br>
<br>
Comments, thoughts and experiences please.<br>
<br>
Thanks,<br>
<br>
