I am trying to load LwIP_TCP_Echo_Server (an example project created by STMicroelectronics) onto a Nucleo_H7S3L8 Evaluation Board (produced by STMicroelectronics) and it's crashing. I had some trouble getting the BootLoader to run through to the JumptoApp function (covered under a different post) and used a workaround fix it.
I set a break point just before the jump and examined the App memory at 0x70000000 (memory mapped). It was all 0xFFFFFFFF. No wonder the code crashed. I used the STM Programmer, and the memory looked ok. Code at 0x70000000 looked like a vector table and definitely not 0xFFFFFFFF. I added the Template_XIP_Boot project to my build as described in the README.md.
I really need to get this piece of ... code to work. Like now. This stuff is basic startup operation. This is an ST example project on ST Nucleo hardware. What's going on? I've seen no other forum posts on my recent issues. Why is everyone else having fabulous success? Am I alone? What's wrong with me?
There are concepts like OctoSPI, XIP, and memory-mapped External Flash which are pretty complex, and I do not want to have to debug them (especially through the HAL).
