Subject: Compiling and running simtrace firmware with a recent toolchain
Message-ID: <20180309170123.64631b9e@second-laptop.localdomain>

Hi,

The simtrace firmware is in the OpenPCD git repository at:
> git://git.osmocom.org/openpcd.git

I used the last revision at the time of writing:
> dc2983d firmware: Makefiles: enable changing toolchain

With a fairly recent gcc version:
> $ arm-none-eabi-gcc --version
> arm-none-eabi-gcc (Arch Repository) 7.3.0
> Copyright (C) 2017 Free Software Foundation, Inc.

Compiling the firmware the usual way works, with many warnings:
> $ make BOARD=SIMTRACE DEBUG=1 TARGET=main_simtrace \
> CROSS_COMPILE=arm-none-eabi-
[...]

Installing that firmware went fine:
> $ sudo dfu-util -d 16c0:0762 -a0 -D ./main_simtrace.bin -R
> dfu-util 0.9

Unfortunately with the new compiler the device gets re-enumerated
continuously:
> usb 4-1: new full-speed USB device number 3 using uhci_hcd
> usb 4-1: new full-speed USB device number 4 using uhci_hcd
> usb 4-1: new full-speed USB device number 5 using uhci_hcd
[...]

Here's what I have on the serial port:

So it gets reset in a loop.

I can get it to work with the following diff:
--- a/firmware/src/simtrace/tc_etu.c
+++ b/firmware/src/simtrace/tc_etu.c
@@ -96,8 +96,8 @@ void tc_etu_init(void)

With the diff I have the following on serial:
