I’m having a problem using a program that is bigger than 150k in a STM32F103ZE (that have 500k).
When I compile and send a program it RUN PERFECT (BOOT 0 in UPLOAD MODE). When I put BOOT 0 in RUN MODE it STOP WORKING.
If I reduce my program program to less than 150k it works in both modes.
Can some one help me?
THIS WORK:
O sketch usa 148828 bytes (28%) de espaço de armazenamento para programas. O máximo são 524288 bytes.
Variáveis globais usam 14016 bytes de memória dinâmica.
THIS NOT WORK

But if I put in RUN MODE (BOOT 0) and RESET it stop WORK.
you could try to run objdump on the elf file using various parameters e.g. -h or -t etc and take a look at where the segments are mapped, e.g. is some global variables mapped into flash instead?
global / static variables should normally live in .bss segment and should be mapped to regions of sram. if the variables are mapped say in .text which is program memory and that is flash, any attempt to write to the variable would crash the program
(btw, i’m suspecting that jumper or pin may not be boot0 after all, if you set boot0 each time you reboot the board would seem to do ‘nothing’, it is waiting for a uart to connect for program upload.)
Yes.

well it won’t be possible to tell from this, but there are tools like arm-none-eabi-objdump (this should be there in your arm-gcc-none-eabi compiler directories).you could try to run objdump on the elf file using various parameters e.g. -h or -t etc and take a look at where the segments are mapped, e.g. is some global variables mapped into flash instead?
global / static variables should normally live in .bss segment and should be mapped to regions of sram. if the variables are mapped say in .text which is program memory and that is flash, any attempt to write to the variable would crash the program
(btw, i’m suspecting that jumper or pin may not be boot0 after all, if you set boot0 each time you reboot the board would seem to do ‘nothing’, it is waiting for a uart to connect for program upload.)
When I reboot and the Boot0 is “enabled” it just wait for UART, that is OK. But after I UPLOAD the code (without reset our change the BOOT0) it automatic run the CODE (like a software reset after the upload).
The error just happen when I put the BOOT 0 in RUN MODE and reset after that, and the program is bigger than 150k.
So the anomaly would be that the <150k sketch runs @0x08000100 in “run mode”…

[edogaldo – Thu Sep 13, 2018 8:07 pm] –
No, the point is that in “run mode” the mcu expects the sketch @ 0x08000000 (or 0x20000000 if boot from ram), any other address is not supported.
So the anomaly would be that the <150k sketch runs @0x08000100 in “run mode”…
I got that! But I think when UPLOADING software WRITE 0x08000100 (“Wrote address 0x08000100 (0.17%)” )it is uploading to 0x08000000. I think I wrote wrong about the adress was setted to 0x08000100. It was setted to 0x08000000.
Be sure you compile and install for address 0x08000000, it should work whichever its length.
https://www.st.com/content/ccc/resource … 164185.pdf
page 15 section 3.1 boot mode selection
boot1 boot0 boot
x 0 flash memory
0 1 system memory (i.e. uart boot loader)
1 1 sram
What exactly means “it does not work”? Do you output data on any serial port?
Which IDE do you use? On which OS?
Please prepare a simple sketch which reproduces the problem.
As test, just allocate a constant variable of size 150kB and do a simple processing of it, and check if it works or not.
