(gdb) help x Examine memory: x/FMT ADDRESS. ADDRESS is an expression for the memory address to examine. FMT is a repeat count followed by a format letter and a size letter. Format letters are o(octal), x(hex), d(decimal), u(unsigned decimal), t(binary), f(float), a(address), ...

Valgrind has a builtin GDB server and can act as a remote target to GDB. It can help to find invalid memory writes, use of uninitialized variables, memory leaks and many other bugs.Serving as an intermediary between Valgrind and GDB, vgdb is a small program but an important one. Valgrin...
multi, you can inspect an issue (such as invalid write, for example) at the point it happened. You can set a breakpoint with GDB and ask Valgrind to provide various diagnostics. You could ask Valgrind whether some variable has been initialized, for example, or you can scan for memory ...
flash erase Erases the flash memory of the target device. getargs Get the arguments for the application. go Starts the target CPU. halt Halts the target CPU. jtagconf Configures a JTAG scan chain with multiple devices on it. memU8 Reads or writes a byte from/to given address. ...
This is because it can take many seconds to scan library sources which would disrupt the Ide during code writing. Hopefully as the next few months progress we manage to optimize and add intelligence to the "deep scan" enabling its use for intellisense. In the meantime, if intellisense is ...
This is very useful for checking if the LuaJIT VM takes up too much memory on the Lua land. Below is an example: (gdb) lgc The current memory size (allocated by GC): 898960 bytes Back to TOC syntax:lgcstat fileluajit21.py
