Re: Intercept the usart isr without resorting to hacking the core

Last time we tried it we reverted because of some issues, but wasn't clear if the issues were due to this change in particular, or to removing -Wall, so it is worth testing, but we need to test it with as many different peripherals as possible. My memory is foggy on all this. However, -Wall does no...

Re: ARM binary disassembler ??

Last night ( my rime) I looked at using my BMP and GDB for this, but had problems loading a bin file rather than an elf. I thought the GDB restore command was supposed to load a bin, but it didnt seem to work, and I couldnt get the code to reset and run. Did you erase flash before trying to load th...

Re: ARM binary disassembler ??

PS. I think something is wrong with the vector table dump as the first 4 byes are zeros where they should be the stack address so it looks like 4 bytes of zero got pre-pended to that listing. $ od -t x4 -v blink.bin | head -15 0000000 20005000 08000171 08000441 08000445 0000020 08000449 0800044d 08...

Re: ARM binary disassembler ??

Thanks Rick I think I'm a little closer to a readable disassembly, by using your settings, but something is still a bit screwy, because I'm getting undefined instructions 8000484: fff9 ffff ; <UNDEFINED> instruction: 0xfff9ffff which probably means that any code after that point is definitely screw...

Re: ARM binary disassembler ??

To decode the vector table: $ od -t x4 -v sketch_feb09a.ino.bin | head -15 0000000 20005000 08000165 080003e1 080003e5 0000020 080003e9 080003ed 080003f1 08000441 0000040 08000441 08000441 08000441 08000441 0000060 08000441 08000441 08000441 080007f9 0000100 08000441 08000441 08000441 08000441 00001...

Re: ARM binary disassembler ??

... objdump -b binary -m arm -D test.bin > test.asm Maybe something like this: $ arm-none-eabi-objdump -b binary -m arm -D -Mforce-thumb --adjust-vma=0x08000000 sketch_feb09a.ino.bin | less ... snipped off the vector table 80000ec: b510 push {r4, lr} 80000ee: 4c05 ldr r4, [pc, #20] ; (0x8000104) 80...

it's not updating last post read for when hit the 'go to first unread' apart from that, it's embrassing that firefox on win-xp from a virtualbox on a debian jessie box is almost normal :oops: stephen That just shows you how badly caching schemes worked back then.

Re: are you playing with board settings? being returned to login screen

Ah... that makes sense. Check your time and date settings, check ntp if you are running that, restart the web service to ensure it has the correct time and date. I suspect it is sitting somewhere in the future, and this is confusing some browsers. Yeah it is definitely a caching issue and my system...

Is this still broken??

It looks like HostGator may have fixed it already

Doesn't feel fixed to me.

What did work for me is using the Developer Tools to disable caching

My old iPad 2 still works absolutely fine ;-)

It probably ignores all cache related features ... My ipad one works also
