Thanks for your replies, Gautier and Alexandre!
After some struggles (with variables &pprzLogFile and
pprzLogFile.fs in the module c-files and compiling paparazzi on
Linux Mint17.1 which worked for v5.4 but not immediately for master)
I've managed to switch to master version
v5.5_devel-555-g3b28ef3-dirty, however file names are still not
created as expected yet.
As shown in the attached screenshot (05.png), the flightrecorder
works but suffers from similar problems regarding the file names as
sdlog does. For the latter the -36 file was overwritten again.
Additionally, after unplugging and replugging the USB cable, a
pprzlog_000.LOG appears with a remarkable date (which might indicate
the final breakthrough for decadal climate prediction ;)).
Thus unfortunately it is not fixed yet in master.
Thank's for your help on this (as well as for the apogee/pprz stuff
as a whole, really a great tool)!
Cheers,
Andreas
PS: If someone is interested in the humid_sht and airspeed_ets sdlog
function, the updated files for master are attached.

I think i know
what is
wrong, i am far from a computer now, but should fix it on
Monday. I think the problem is i don't chek that the
numering part is
really only Digit, and if it's not, atoi will fail.

Hi,
Thank you for reporting the issue, we'll have a look at
this. In the mean time, the sdlog in master has changed a
bit in order to log into several files, with "flight
recorder" feature using the periodic telemetry system (https://github.com/paparazzi/paparazzi/pull/1144,
to be documented...).
Maybe the issue is fixed in master now, but we still need to
check for both master and v5.4.

Hi,
I'm using the SDLOG function for the "humid_sht" and
"airspeed_ets" modules (TEMOD-I2C-R1 would be a next
candidate ...) on the APOGEE board (see below at PS for
the files I use for SDLOG).
It works fine, however the filenames that are created by
SDLOG cause reproducible troubles:
sometimes the mechanism of counting up the file name
numbers (depending on the already existing files) does not
work.
Instead there are filenames including negative numbers
(-36 and -2147483648 (smallest 4byte integer) are
frequently appearing) and these files are frequently
overwriting old files with the same odd name. We have lost
some measurement data (very very early in the morning :))
by this, when we switched the plane off and on after
flight.
Please find four directory listing screenshots attached,
each captured after switching off and on the APOGEE and
after some time of measurement plugin in the USB cable to
the computer respectively. First (01.png) everything is
fine (pprzlog_001.LOG), next (02.png) there is an
additional file pprzlog_-2147483648.LOG (ugly but
containing the new data), at the next measurement
(003.png) we get a pprzlog_-36.LOG which is finally
(04.png) overwritten (see the size and date of the file).
It seems, the integer which is used for the filename is
sometimes uninitialized or so.
I found the function "getNextFileName" in
sw/airborne/subsystems/chibios-libopencm3/sdLog.c
But there the integer maxCurrentIndex is initialized to
zero in line 248.
Can this be a hardware or filesystem issue? However, it
happens on other APOGEE boards too. The filesystem is 8GB
FAT and it happens on other (class 10) micro-SD cards too.
I'm running the APOGEE on 3S Lipos and 4S Lipos and don't
think it's a power issue.
I'm currently using Paparazzi version
v5.4.2_stable-0-g21e8716-dirty
I know that this didn't happen half a year ago or so,
however I cannot say exactly with which version ...
Can someone please help in finding this bug?
Thanks!!!
Andreas
PS the modified files for using SDLOG with humid_sht and
airspeed_ets were reported formerly here (still not
included in git):
