Honestly, I haven't got a clue what's in the image or if it even works, but it could be a led blinker or Linux. Perhaps everything is working fine, and it's just that your application is somehow broken. For example by lighting up different LEDs depending on what it is doing.
#FUSESOC CYGWIN TUTORIAL SIMULATOR#
This would require you to convert the uImage file to verilog hex and load it into the simulator with -spi_flash_file=/path/to/file.vh The bootloader doesn't provide any visible clues about what is going on. At this point it's hard to tell what could be wrong. The spi_uimage_loader (which I assume you are using as the bootrom) expects the application image to use the uImage format. I figured it was better to use an existing format instead and chose therefore uImage, which is the same format as uBoot is using. It was an old, very simple image format that just used the first word to indicate the size of the image. We should probably make a better fix forīin2binsizeword is obsoleted. For now, I think your best option wouldīe to copy or1k_uart., and make your own version where you can set aīase address to your second UART. Looking at or1k_uart.c now, I realize that these functions aren't reallyīuilt to handle additional UARTs. _write in libgloss, which in turn calls or1k_uart_write
#FUSESOC CYGWIN TUTORIAL CODE#
Up, a printf in your code calls the printf function in newlib, which calls _or1k_board_uart_base, which in turn is defined in libboard. It expects to find a UART at base address
Specifically for the UART, there is or1k_uart.c which handles the OS, such as Linux, the answer is differentĪnyway, the bare-metal toolchain (or1k-elf-) uses newlib, which in turnĬalls libgloss to carry out the hardware-dependent tasks, such as readingĪnd writing characters from/to a UART. I assume that you are running a bare-metal program.

For now, I think your best option would be to copy or1k_uart., and make your own version where you can set a base address to your second UART. Looking at or1k_uart.c now, I realize that these functions aren't really built to handle additional UARTs. So to sum it up, a printf in your code calls the printf function in newlib, which calls _write in libgloss, which in turn calls or1k_uart_write It expects to find a UART at base address _or1k_board_uart_base, which in turn is defined in libboard. Specifically for the UART, there is or1k_uart.c which handles the low-level functions.

The part about openocd should be very similar on the de0 nano Recommend you to read up a bit on openocd. Write the program to RAM and run it directly from there. There are several ways to load a program.
