2019-03-22app/debugging: unify path to hello binaryKurt Kanzenbach
For GDB sometimes the hello binary is located in /home/devel/work and sometimes in /home/devel/jan. Unify it. Signed-off-by: Kurt Kanzenbach <kurt@linutronix.de>
2019-03-06app/debugging: add description slide for address sanitizerKurt Kanzenbach
Add a brief introduction about what the address sanitizer actually is and what types of bugs in can find. That's useful for our customers. Requested-by: Holger Dengler <holger.dengler@linutronix.de> Signed-off-by: Kurt Kanzenbach <kurt@linutronix.de>
2019-02-28embedded-devel: remove unnecessary "cut" in commandJohn Ogness
The -dM argument shows the built-in macros. Cutting the #define from the output not only make the command unnecessarily complex, but also works against illustrating that they are macros. Signed-off-by: John Ogness <john.ogness@linutronix.de>
2019-02-28app/debugging: add address sanitizer exampleKurt Kanzenbach
The address sanitizer is a useful tool for debugging lots of memory related bugs such as heap/stack overflows, user after frees and much more. Signed-off-by: Kurt Kanzenbach <kurt@linutronix.de>

2019-02-07fix various typos and wrong commands in slidesHolger Dengler
Fixes for: - missing variable definition in Makefile - wrong serial device in kernel parameters - missing trace-cmd subcmd and wrong parameter (sched_switch is an event, not a plugin) - missing #include in example code - fix copy&paste leftover Signed-off-by: Holger Dengler <dengler@linutronix.de> Reviewed-by: Kurt Kanzenbach <kurt@linutronix.de>
2019-01-28profiling - gprof: use no PIE compiler and linker optionManuel Traut
PIE is enabled in the gcc of Debian/stretch by default. However the gprof in stretch isn't able to produce any output if PIE is enabled. This is also documented here: https://bugs.debian.org/cgi-bin/bugreport.cgi?bug=854704 Disable PIE for the moment to get some gprof output. However i'm not able to find out how to disable PIE if compiling and linking is done in two steps. Therefore this is just removed. Signed-off-by: Manuel Traut <manut@linutronix.de>

2018-11-06app-debugging: remove obsolete slidesJohn Ogness
Trainers should use DEBUGGING_TOOLS instead. Signed-off-by: John Ogness <john.ogness@linutronix.de>
2018-08-31embedded-devel: fix loader env-var table to fitJohn Ogness
The table showing the dynamic loader environment variables was running off the edge of the slide. The main reason was because the description column was too wide. Reduce the description column width. Signed-off-by: John Ogness <john.ogness@linutronix.de>
2018-05-15application-devel: git-basics: remove germanJohn Ogness
The section title was german. Change it to english. Signed-off-by: John Ogness <john.ogness@linutronix.de>
2018-05-15application-devel: cleanup git-basics slide textJohn Ogness
Use a consistent and easy to read capitalization scheme. This patch fixes some minor typos discovered during capitalization changes. Signed-off-by: John Ogness <john.ogness@linutronix.de>
2018-04-19replace *all* tabs with spacesJohn Ogness
There are times when tabs are allowed and times when they are not. Let's just simply never use tabs for anything. This makes it easy to find presentations where tabs were accidentally inserted. Signed-off-by: John Ogness <john.ogness@linutronix.de>
2018-04-19embedded-devel: fix command line to match exampleJohn Ogness
The following slide shows hello2 using DT_RPATH, so set the output to hello2 when compiling. Signed-off-by: John Ogness <john.ogness@linutronix.de>

2018-02-20remove german slides when english are availableJohn Ogness
Remove german slides if a completely translated english version is available. For slides that have been translated to english, but do not contain all the information of the german slides, the german slides are still available. But they are only available for reference. That will not be built. Signed-off-by: John Ogness <john.ogness@linutronix.de>

2018-02-20debugging-tools: add symbol reinsert and PIE infoJohn Ogness
PIE binaries are now the default, so let's talk about them. Particularly for mtrace it is important to understand. Signed-off-by: John Ogness <john.ogness@linutronix.de>

PIE binaries are now the default, so let's talk about them. Signed-off-by: John Ogness <john.ogness@linutronix.de>
2018-02-20embedded-devel: add LD_TRACE_PRELINKINGJohn Ogness
Since PIE binaries are created by default now, it has become important to see where the binaries are mapped in memory. LD_TRACE_PRELINKING is the dynamic loader environment variable to see that. $ env LD_TRACE_PRELINKING=1 ./hello | grep '=>' Signed-off-by: John Ogness <john.ogness@linutronix.de>
