15:12 <wtywtykk> Hi, is there any way to use FLM files in openocd? Many manufacturers seem to only provide keil's FLM download algorithms.

19:02 <borneoa_> wtywtykk: openocd use its own internal way to code the flash algorithm. Just for curiosity I checked what FLM files are. It's part of ARM sw, to be checked if license allows integration in openocd and if it makes sense to use it https://arm-software.github.io/CMSIS_5/Pack/html/flashAlgorithm.html

19:04 <borneoa_> wtywtykk: so far, I'm not aware of any patch proposed for supporting FLM

19:32 <wtywtykk> I found Sysprogs has implemented something similar in their release. They both use ELF file, and call functions in ELF to write/erase flash. https://github.com/sysprogs/openocd/blob/master/src/flash/FLASHPlugin.c

20:25 <borneoa_> wtywtykk: the code from sysprogs is not the same as arm FLM. Sysprogs search in the elf the symbol "FLASHPlugin_InitDone" https://github.com/sysprogs/openocd/blob/72c3119d65a1b8efec5c4a3a81333518d960eaa8/src/flash/FLASHPlugin.c#L332

20:26 <borneoa_> wtywtykk: while arm code has other symbols https://github.com/ARM-software/CMSIS_5/blob/244e279d7989057d0eef417dfefa806062ec9afd/Device/_Template_Flash/FlashOS.h#L62

20:28 <borneoa_> wtywtykk: cannot use an arm FLM with sysprogs code

20:31 <borneoa_> wtywtykk: the arm code is under Apache 2 license. I think it's not compatible with GLP v2. At the end we only need the declarations in that file.h... to be checked.

20:42 <borneoa_> https://github.com/pyocd/FlashAlgo

21:53 <karlp> pretty suee apache 2 can be one way used in gpl.

21:53 <karlp> apache2 being an actually free license

21:55 <karlp> apache agrees with me https://www.apache.org/licenses/GPL-compatibility.html

22:48 <borneoa_> karlp: only with GLPv3

22:49 <borneoa_> karlp: "Despite our best efforts, the FSF has never considered the Apache License to be compatible with GPL version 2..."

22:51 <borneoa_> karlp: but we probably don't care. Just sent a mail to the list on this.
