Hello everyone,I'm trying to interface a microSD card using FileX on a custom board with an STM32H747IIT6.The microSD card is connected to the SDMMC1 peripheral using a 4-bit wide bus, with external pull-ups on the data lines.Initially, we used FATFS...

Hello mbarg.1,Thank you for your response. I now understand how and where the RX buffer is placed.I am aware that the IP address must be set, which is why I am using DHCP. I checked the network traffic with Wireshark.Sometimes, I receive a DHCP reque...

I found the problem: I messed up the TEX level in the Memory Protection Unit settings.I mistakenly set the TEX level for the second region instead of the first region.I’ve attached the latest code for reference. This code runs without any faults on m...

I think the srand problem and the new hard fault are two separate issues. The srand issue was caused by the linker script. I feel like the hard fault is a software bug where the &hdr->sipaddr gets placed unaligned in the microcontroller's memory.Shou...
