Good Moorning,
I open this post, because i am working in a proyect with Ethernet, but i have a strange issue that i cant find the source of problem. I hope you can help me, Thanks.
The problem, is that in optimization O0 the proyect not work propertly, it occurs a hardfault handler in parte of code that dont have sense. While if i use the optimization Oz, work propertly.
With other levels of optimization, appear same error that O0.
I indicate aditional information of the proyect:
MCU: STM32F779NI ETH_Controller: KSZ9031MNX Library_Ethernet: LWIP ARM Compiler: 6.11
Also, comment that i was modify the Scatter file. I modify it because of i need have reserved RAM (MPU) for the DMA Ethernet.
Thanks for your help.
Kinds Regards.
