Bugs in project STemwin OoB demo for DISCOVERY STM32h747I

[Jvela.11]

I found a bug in the project named "STemWin-STM32H747I-DISCO-OoB, after some time in the STLink uart appears messages about memory leaking :

_cbBk() : Memory leak detected after running the module Dual Core : 298704/298440

In this case the application continue running after the messages appears.

The other bug only happen when I navigate and enter in "dual core" option .I'm able to see the four videos running and the fractal render ,but after a while it freezes and appears the next message :

assertion "REENT malloc succeeded" failed: file "/build/gnu-tools-for-stm32_9-2020-q2-update.20201001-1621/src/newlib/newlib/libc/stdlib/rand.c", line 78

I don't understand why this fw behaves different than the demo binary wich work perfectly.

I've saw this issue in others post without solution, I hope this one finally resolve.

Thanks in advance !

Hi @Jvela.1​ ,

I'm trying to reproduce the issue on my side using MDK-ARM with the workspace STemWin-STM32H747I-DISCO-OoB available under STM32Cube_FW_H7_V1.9.0. I'll keep you informed on this regard.

Please let me know if you are following the same steps as well and using the same configuration.

But if you would like to execute the demonstration as is, please follow the description provided in the readme.txt file available in the path STM32Cube_FW_H7_V1.9.0\Projects\STM32H747I-DISCO\Demonstrations.
