STM32F407VET6 Black Board freeze

Post by bellad » Wed Jun 03, 2020 7:53 am

Hello,
with my prog , when i test on the STM32F407VET6 Black Board crashed
i no understand with 192k sram
can you help
thank

There are more reasons for hanging than RAM exhaustion. Perhaps one of those pins you changed is essential for the proper operation of the board? Clock pins, serial I/O pins, USB pins, external flash pins, sd card pins, ...

To debug, remove half your code, try again, etc - until you have isolated the pin(s) that cause(s) this.

it's

Code: Select all

mem=[mchp,mchf,mcha,msdb,mchv,mesc,mcui,msam,msal,mwc,mbur,ment]
crashed !!!!
I do not understand anything anymore
i need array mem[] with variable ( exp: mchp = 0 or 1 )
it takes a lot of memory ??

i try only :

Code: Select all

mchp=0
mchf=0
mcha=0
msdb=0
mchv=0
mesc=0
mcui=0
msma=0
msal=0
mwc=0
mbur=0
ment=0

mem=[mchp,mchf,mcha,msdb,mchv,mesc,mcui,msam,msal,mwc,mbur,ment]
it's crash

i have to use

Code: Select all

mem=[0,0,0,0,0,0,0,0,0,0,0,0]
But I do not know why

I will suspect that 1 of the pin your trying to use is connected to something that is important to the running of the MCU.

Try this commit out every line except the first 1 where you import then uncommit 1 line at a time till you find which line is causing the crash then check the schematic for what is connected to that line.
