I am working on an STM32f767 project with LWIP and MQTT. Everything seemed to work for a while but eventually, I received the following assert: "pbuf_free: p->ref > 0..." which caused it to crash sometimes; but sometimes it will continue to work wit...

I have a custom board that used to work with an older version of CubeMx-generated code, but with recent changes, my board no longer works. I made modifications in ethernetif.c to accommodate the known bug. but the board no longer responds to ping fro...

I have a project that uses TouchGFX with an external parallel SRAM for the frame buffer and double buffer. Everything works as expected, But if I try to declare other variables in the external SRAM (A section defined outside of the display buffer ran...

ethernetif is attached to the original message; ethernetif.c is the same between the 2 versions.

no, I am using STM32F767BIT6. The strange thing is: that it works with an earlier version of CubeMx, but I also made changes in other parts of the code (nothing that should affect the ethernet).

yes, **bleep**S_CFG is defined in another file. I think it is obvious that it is a struct type.

yes, my framebuffer works just fine. I was able to get my struct variable working (it no longer crashes) by forcing my struct alignment with "__attribute__((aligned(4)))". I guess I do not have access to individual bytes that are not aligned by 4. I ...

I'm using the SDRAM for TouchGFX. It crashes only when I try to define a struct in SDRAM.

TouchGFX Frame Buffer in External Shared SRAM

I am working with a custom board: I have a Touchgfx project that seems to work fine with my custom loader, but if I place text in the external flash it will hard fault. Please note that when I place images/Icons it works fine.

Is it possible for TouchGFX to generate the text file and images into a binary/hex file separately when generating code? I have a custom bootloader that i want to use to put the resources on an external QSPI flash during firmware update.
