Re: Cortex-M0 bugs: 88167, 88656

Yup, I just wanted to throw that out there for the future, in case it helps you save some time.

Best,

Re: Cortex-M0 bugs: 88167, 88656

Giovanni, In previous situations like this, I've had success doing something like the following: #if defined __GNUC__ #if ( __GNUC__ > 5 ) && ( __GNUC__ < 10 ) #define GCC_VERSION ( __GNUC__ * 10000 + __GNUC_MINOR__ * 100 + __GNUC_PATCHLEVEL__ ) #if ( __GNUC__ == 7 ) && ( GCC_VERSION...

Re: Porting old EXT driver implementation to Chibi_19

Ahaa, and it looks as though the RTCv2 driver already uses it to set those IRQs up properly. I guess I should have read the driver code first.

Thanks as always,

Porting old EXT driver implementation to Chibi_19

Hi, I have an older project I think I used Chibi_16 vintage. As discussed in this posting: http://www.chibios.com/forum/viewtopic.php?t=3319 We figured out a way to use EXTI17 as a wakeup source. However, I relied on the EXT driver to set up the IRQ. Now that PAL has replaced EXT, it seems to be onl...

Re: Zip compression on a micro

Thanks guys for the helpful insight: @Giovanni: Yep, I did look briefly at p7zip, but it seems it is LGPL which will not be compatible with static linkage. Also, it is written predominantly as C++ code which I don't think would fly for this project. @Polux Yes, this is a case of the end-user reqs do...

Zip compression on a micro

Hi all, I was asked today about implementing zip file compression on a micro, most likely using fatfs on top of an SDCard. Just wondering if anyone has blazed this trail before and could offer any advice on existing software (preferably free licensed, but commercial licenses wouldn't necessarily be ...

Re: C++ exceptions in cortex-m7 vs. cortex-m4

Unfortunately, those changes do not seem to fix my original issue. I tried both trunk (r13183), as well as stable_19.1.x branch (r13176) from SVN. I verified both had the line steved mentioned in the corresponding rules_code.ld. I tried with both gcc-arm-none-eabi-7-2017-q4-major and gcc-arm-none-ea...

Re: GCC 9

That's a shame they missed merging the cortex-m0 fix prior to the last round of releases. Giovanni, based on what you've seen so far (and ignoring the cortex-m0 issue), is GCC 9 shaping up to be decent across most of the spectrum? I recall reading the last benchmark thread done between GCC 7 and 8, ...

Re: C++ exceptions in cortex-m7 vs. cortex-m4

Hi Giovanni,

I'd be happy to test, it will be at least mid next week before I'll be near that hardware. Should I be testing off the trunk, or 19.x maintenance branch, or both?

Dave
