Honored Contributorkernal build on custom board
I am trying to build the uC linux kernal for a custom board. I am not using an Altera or Microtronix board. The kernal build fails wrt the JTAG UART. It fails, apparently, in the same spot whether or not the JTAG UART is part of the NIOS core or not.
Any thoughts here? IRQ number wrong? Base address wrong? Something I have to change when configuring the kernal? Here is a list of the errors: Any and all help is much appreciated by this non-linux rookie.
