@ -22,12 +29,58 @@ The procedure to create a patch is essentially:
- correct the patch and re-send it according to review feedback
Your patch (or commit) should be a "good patch": focus it on a single
issue, and make it be easily reviewable. Don't make
issue, and make it easily reviewable. Don't make
it so large that it's hard to review; split large
patches into smaller ones. (That can also help
track down bugs later on.) All patches should
patches into smaller ones (this will also help
to track down bugs later). All patches should
be "clean", which includes preserving the existing
coding style and updating documentation as needed.
coding style and updating documentation as needed. When adding a new
command, the corresponding documentation should be added to
@c doc/openocd.texi in the same commit. OpenOCD runs on both Little
Endian and Big Endian hosts so the code can't count on specific byte
ordering (in other words, must be endian-clean).
There are several additional methods of improving the quality of your
patch:
- Runtime testing with Valgrind Memcheck
This helps to spot memory leaks, undefined behaviour due to
uninitialized data or wrong indexing, memory corruption, etc.
- Clang Static Analyzer
Using this tool uncovers many different kinds of bugs in C code,
with problematic execution paths fully explained. It is a part of
standard Clang installation.
To generate a report, run this in the OpenOCD source directory:
@code
mkdir build-scanbuild; cd build-scanbuild
scan-build ../configure
scan-build make CFLAGS="-std=gnu99 -I. -I../../jimtcl"
@endcode
- Runtime testing with sanitizers
Both GCC and LLVM/Clang include advanced instrumentation options to
detect undefined behaviour and many kinds of memory
errors. Available with @c -fsanitize=* command arguments.
Example usage:
@code
mkdir build-sanitizers; cd build-sanitizers
../configure CC=clang CFLAGS="-fno-omit-frame-pointer \
-fsanitize=address -fsanitize=undefined -ggdb3"
make
export ASAN_OPTIONS=detect_stack_use_after_return=1
src/openocd -s ../tcl -f /path/to/openocd.cfg
@endcode
Please consider performing these additonal checks where appropriate
(especially Clang Static Analyzer for big portions of new code) and
mention the results (e.g. "Valgrind-clean, no new Clang analyzer
warnings") in the commit message.
Say in the commit message if it's a bugfix (describe the bug) or a new
feature. Don't expect patches to merge immediately

Each time when OpenOCD fills data to CPU (via dongle, via dmseg), CPU takes it and proceeds in executing the handler. However, since handler is in a assembly loop,
CPU comes to next instruction which also fetches data from FASTDATA area. So it stalls.
Then OpenOCD fills the data again, from it's (OpenOCD's) loop. And this game continues untill all the data has been filled.
After the last data has beend given to CPU it sees that it reached the end address, so it proceeds with next instruction. However, rhis instruction do not point into dmseg, so
After the last data has been given to CPU it sees that it reached the end address, so it proceeds with next instruction. However, this instruction do not point into dmseg, so
CPU executes bunch of handler instructions (all prologue) and in the end jumps to MIPS32_PRACC_TEXT address.
On it's side, OpenOCD checks in CPU has jumped back to MIPS32_PRACC_TEXT, which is the confirmation that it correclty executed all the rest of the handler in RAM,

In this case, we can lower the JTAG frquency and try again, bacuse most probable reason of this failure is that we tried FASTDATA upload before CPU arrived to rise PrAcc (i.e. before it was pending on access).
In this case, we can lower the JTAG frequency and try again, because most probable reason of this failure is that we tried FASTDATA upload before CPU arrived to rise PrAcc (i.e. before it was pending on access).
However, the reasons for failure might be numerous : reset, exceptions which can occur in debug mode, bus hangs, etc.
If lowering the JTAG freq does not work either, we can fall back to more robust solution with patch posted below.
To summarize, FASTDATA communication goes as following :
-# CPU jumps to Debug Exception Vector Location 0xFF200200 in dmseg and it stalls, pending and waiting for EJTAG to give it first debug instruction and signall it by putting PrAcc to "0"
-# CPU jumps to Debug Exception Vector Location 0xFF200200 in dmseg and it stalls, pending and waiting for EJTAG to give it first debug instruction and signal it by putting PrAcc to "0"
-# When PrAcc goes to "0" CPU execute one opcode sent by EJTAG via DATA reg. Then it pends on next access, waiting for PrAcc to be put to "0" again
-# Following this game, OpenOCD first loads handler code in RAM, and then sends the jmp_code - instruction by instruction via DATA reg, which redirects CPU to handler previously set up in RAM
-# Once in RAM CPU does not pend on any instruction, but it executes all handler instructions untill first "fetch" to Fastdata area - then it stops and pends.
-# Once in RAM CPU does not pend on any instruction, but it executes all handler instructions until first "fetch" to Fastdata area - then it stops and pends.
-# So - when it comes to any instruction (opcode) in this handler in RAM which reads (or writes) to Fastdata area (0xF..F20.0000 to 0xF..F20.000F), CPU stops (i.e. stalls access).
I.e. it stops on this lw opcode and waits to FASTDATA TAP command from the probe.
-# CPU continues only if OpenOCD shifted in SPrAcc "0" (and if the PrAcc was "1"). It shifts-out "1" to tell us that it was OK (processor was stalled, so it can complete the access),
and that it continued execution of the handler in RAM.
-# If PrAcc was not "1" CPU will not continue (go to next instruction), but will shift-out "0" and keep stalling on the same instruction of my handler in RAM.
-# When Fastdata loop is finished, CPU executes all following hadler instructions in RAM (prologue).
-# In the end of my handler in RAM, I jumps back to begining of Debug Exception Vector Location 0xFF200200 in dmseg.
-# When Fastdata loop is finished, CPU executes all following handler instructions in RAM (prologue).
