I am developing a microblaze system that has more than four uarts. I am looking for some direction on where I need to apply configuration or source changes to support more than the default devices ttyS0-ttyS4. Currently, my boot output for uarts looks like this:
uartlite.0: ttyS0 at MMIO 0x40600000 (irq = 10) is a uartlite
uartlite.1: ttyS1 at MMIO 0x60030000 (irq = 2) is a uartlite
uartlite.2: ttyS2 at MMIO 0x60040000 (irq = 3) is a uartlite
uartlite.3: ttyS3 at MMIO 0x60050000 (irq = 4) is a uartlite
uartlite: probe of uartlite.4 failed with error -22
uartlite: probe of uartlite.5 failed with error -22
I imagine it is a simple fix, I just don’t know where to start looking.
