Hi, I am new and I recently have started using OR1200. I have done simple project with UART and SRAM memory to write from processor some data to TestBench via UART. I am using simulator for this.
I would like to try boot simple Linux on OR1200. My hardware contains the following peripherals: - INTGEN - UART - SRAM memory I have prepared linux binary file, however I see that some code for exceptions is in wrong address space. Should start from 0x100 address but starts from 0x800 address. When I created assembler from binary file everything looks ok. I would like to put this simple Linux directly to the SRAM memory but it is not working. I tried to use bootloader which is in SROM memory, but this is not working also. I am getting one of two problems: - Processor hangs in die_if_kernel function - bus error - there is reading transaction on data bus from very high address I do not know what I am doing wrong. This is first time when I try to boot linux on SoC. Has anyone some simple example how to configure and prepare Linux for very simple hardware with UART?
