There is a DynamicLoaderStatic which will load files at the address that they are specified in the object files. When you load your ELF file using:<div class=""><br class=""></div><div class="">(lldb) file /path/to/foo.elf</div><div class=""><br class=""></div><div class="">What does:</div><div class=""><br class=""></div><div class="">(lldb) target list</div><div class=""><br class=""></div><div class="">show as the output? You might want to specify "none" for both the vendor and OS in your target triple when creating your target:</div><div class=""><br class=""></div><div class="">(lldb) file --arch armv7-none-none /path/to/foo.elf</div><div class=""><br class=""></div><div class="">This specifies there is no vendor (first "none" in the triple) and no operating system (second "none" in the triple). The target's triple helps it select the right plug-ins to use like the dynamic load plug-in (which tells LLDB where sections from binaries got loaded), runtime plug-ins and much more.</div><div class=""><br class=""></div><div class=""><br class=""></div><div class="">So you might try:</div><div class=""><br class=""></div><div class="">(lldb) target modules load --load --set-pc-to-entry --slide 0 --file /path/to/foo.elf</div><div class=""><br class=""></div><div class="">Or, you can specify the addresses of all the sections using:</div><div class=""><br class=""></div><div class="">(lldb) target modules load --load --set-pc-to-entry --file /path/to/foo.elf .text 0x1000 .data 0x2000 ....</div><div class=""><br class=""></div><div class="">This allows you to completely control where each section goes and possibly skip other sections. It also informs LLDB that sections have been loaded at specific addresses.</div><div class=""><br class=""></div><div class="">FYI: We will have to tweak LLDB for baseboard support as it has been used bit by a few folks (check the "svn blame" for who added the "--load" option and possibly contact them) but I am sure it needs to be improved.</div><div class=""><br class=""></div><div class="">So try specifying "--arch <arch>-none-none" and see where that gets you. It should select the right dynamic loader plug-in for you. </div><div class=""><br class=""></div><div class="">A bit more explanation about loading. LLDB has the notion of "file addresses" and "load addresses". A file address is valid for one file only, and it is the same as the addresses that are contained within the object file (ELF, Mach-O, COFF). When breakpoints are set by file + line or by name, we resolve these to "section .text + 100 in file foo.elf". Breakpoints can't be set until a section has a "load address" which will tell us where each section actually is mapped inside the process being debugged. For bare boards there is no dynamic linker that tell us '".text" was loaded at address 0x1230000'. If the DynamicLoaderStatic is selected for a target, which is done by having no OS in the target triple for the target, it will set the load address for the sections to match the "file addresses" and breakpoints will then be set. When a section is "loaded", a message is sent around LLDB to indicate a section was loaded, and all breakpoints will now be able to resolve themselves (get the "load address" for each "file address" for each breakpoint) and they will be set in the debugged process. Your extra step where you need LLDB to load your ELF file is now in the mix as well.</div><div class=""><br class=""></div><div class="">So I would recommend:</div><div class="">1 - create your target first:</div><div class=""> (lldb) file --arch armv7-none-none /path/to/foo.elf</div><div class="">2 - attach to the baseboard</div><div class=""> (lldb) gdb-remote ....</div><div class="">3 - load the file in memory</div><div class=""> (lldb) target modules load --load --set-pc-to-entry --slide 0 --file /path/to/foo.elf</div><div class="">4 - set breakpoints now</div><div class=""> (lldb) breakpoint set ...</div><div class=""><br class=""></div><div class=""><br class=""></div><div class="">Usually you can set the breakpoints before your attach, but in your case you probably want to load the ELF file before you set breakpoints, otherwise you might end up setting breakpoints as soon as the "gdb-remote ..." attach happens since the DynamicLoaderStatic will correctly set the load addresses of all your sections after attaching which will cause breakpoint to resolve and attempt write traps to memory. Then if we load the ELF file in step #3 and when it writes all of the ELF sections to memory it will overwrite the breakpoint traps we set. So try the above flow and let us know how things go.</div><div class=""><br class=""></div><div class="">Greg Clayton</div><div class=""><br class=""></div><div class=""><br class=""></div><div class=""><br class=""></div><div class=""><div><blockquote type="cite" class=""><div class="">On Sep 19, 2017, at 11:21 AM, Tatyana Krasnukha <<a href="mailto:Tatyana.Krasnukha@synopsys.com" class="">Tatyana.Krasnukha@synopsys.com</a>> wrote:</div><br class="Apple-interchange-newline"><div class=""><div class="WordSection1" style="page: WordSection1; font-family: Menlo-Regular; font-size: 12px; font-style: normal; font-variant-caps: normal; font-weight: normal; letter-spacing: normal; text-align: start; text-indent: 0px; text-transform: none; white-space: normal; word-spacing: 0px; -webkit-text-stroke-width: 0px;"><div style="margin: 0in 0in 0.0001pt; font-size: 12pt; font-family: 'Times New Roman', serif;" class=""><span style="font-size: 11pt; font-family: Calibri, sans-serif;" class="">Hello,<o:p class=""></o:p></span></div><div style="margin: 0in 0in 0.0001pt; font-size: 12pt; font-family: 'Times New Roman', serif;" class=""><span style="font-size: 11pt; font-family: Calibri, sans-serif;" class=""><o:p class=""> </o:p></span></div><div style="margin: 0in 0in 0.0001pt; font-size: 12pt; font-family: 'Times New Roman', serif;" class=""><span style="font-size: 11pt; font-family: Calibri, sans-serif;" class="">‘target modules load -lp’ fails with error “one or more section name + load address pair must be specified”, works only with --slide option.<o:p class=""></o:p></span></div><div style="margin: 0in 0in 0.0001pt; font-size: 12pt; font-family: 'Times New Roman', serif;" class=""><span style="font-size: 11pt; font-family: Calibri, sans-serif;" class=""><o:p class=""> </o:p></span></div><div style="margin: 0in 0in 0.0001pt; font-size: 12pt; font-family: 'Times New Roman', serif;" class=""><span style="font-size: 11pt; font-family: Calibri, sans-serif;" class="">Another issue is that if breakpoint is set, Process::WriteMemory return zero and ObjectFile::LoadInMemory interprets it as an error without setting appropriate status.
