hi,

i search and search but i cant find where i can change Vector Table base location in memory.map i can find .text 0x08004000 0x718  *(.isr_vector .isr_vector.*)  .isr_vector 0x08004000 0x124 ..\obj\startup_stm32f10x_md_vl.o  0x08004000 g_pfnVectors  *(.text .text.* .gnu.linkonce.t.*)   in memory.ld      rom (rx) : ORIGIN = 0x08004000, LENGTH = 0x00002000 but i need to change vector table address to 0x08000000 NVIC_SetVectorTable(NVIC_VectTab_FLASH, 0x08000000);  - this isnt working ..... i am using stm32f100 and coocox ide ....

Not familiar with your compiler/assembler. The vector table, as used by the M0, has TWO entries in the front portion. The initial Stack Pointer, which should point into a higher area of RAM, and the initial Program Counter (aka ResetHandler function)

+0 SP+4 PC+8 NMI Handler+12 Hard Fault Handler...

Thanks, Clive,

Sorry about late reply.  Thanks for valuable STM32 insight (not just this post... MANY of your posts are VERY helpful.) I'm using the ImageCraft (Palo Alto, CA) ICC/Jumpstart ARM C compiler for STM32F0xxx parts; The ICC compiler supports a bunch of different STM 32 ARM devices.  For some reason, the SP pointer was not described... I guess for obv. reasons.  (i.e. keep me away from producing a BRICK!) I find that the Imagecraft ICC compiler was free (~30 days/ 64KB, etc.) and it was easy to use, so ended up purchasing a license ($99.USD) and it performs really fast (~5K lines+ in ~3 or 4 seconds.)  I had used the ICC compiler many years ago for a Motorola uC, so I was slightly familiar with their old (ancient) compilers. Oh, and a single menu selection downloads the code to the USB-connected device... I can change lines, re-comp and re-upload in less-than ~30 seconds (64KB.) At first, I tried GCC (SLOWWWW Compile!!!! And, LONG TIME TO INSTALL!!!!)  Plus the amount of crappo GCC place onto my laptop was astounding! Also, I tried the ST Cloud solution:  Very robust, very complete!  Very nice cloud solution ... but very hard to perform rapid prototyping. I like to fix, test, test, test, fix... Sometimes re-compile each minute until solution works. So, I needed a quick compiler solution. I suspect that in future, the cloud will be the ONLY way to compile.  (Imagine a cloud supercomputer compiling your code [and everyone else's] ....) Regarding the ICC Compiler: The most important thing I find, is that the installation time is minutes.    Plus, I like to cycle test rapidly during prototyping.  Some of the other compilers I looked at cost too much $$$.  The Imagecraft compiler is the right price and super performance. ImageCraft are a small company, so when you ask for help, you get the CEO or one of the few developers.  This helps a lot. If you get a chance, you should consider trying the ImageCraft compiler. (BTW: I loved your reply concerning ADC and DMA!  Very good work.  Thanks!] -Chris p.s. I do not have any relationship with ICC except that I bought their compiler license.
