compile failure for Arduino Uno

I'll just post the session.

Thanks.

Looks like you need to chmod u+x scripts/gcctest.pl

I don't think the rmdir error is a big deal, so let's not worry about it yet.

No, the issue is the compile error with src/config.h - it doesn't like me trying to compile with an Arduino Uno. But just for the record,

macbookair2:/Users/spectre/src/TestSerial/% chmod +x scripts/gcctest.pl
macbookair2:/Users/spectre/src/TestSerial/% make CONFIG=config-arduino clean all

The issue appears to be that config.h only has support for CONFIG_HARDWARE_VARIANT == 1. Is it still the same dummy board_init() function for other variants?

#if CONFIG_HARDWARE_VARIANT == 1
/* ---------- Hardware configuration: HEXTIr v1 ---------- */

static inline void board_init(void) {
}

#else
#  error "CONFIG_HARDWARE_VARIANT is unset or set to an unknown value."
#endif

My apologies. Use:

make CONFIG=config clean all

I made the default config file the arduino build. You might need to adjust the COM and such in config to suit your board.

[classilla]

Okay, I misunderstood what you were doing here. I thought this was HEXTIr minus everything except the UART, but in this case it's really just the UART. How did you send the text file and monitor data_available?

(I did build and flash it to the Uno, so that much is working)

[go4retro]

I used RealTerminal and sent a large text file to the UNO, and then watched the RS232 output. Any terminal seems like it would work for this. I think I used 9600 to allow me to see the progress.

[classilla]

Okay, then I must have screwed up something, because all I'm getting from the TX/RX pins is garbage at any baud rate (tried 300, 600, 1200, 2400, 4800, 9600, 19200, 57600 and 115200). The lights blink on the Uno if I type keys, but the output is nonsense. Or is that what you saw?

More specifically at 9600bps I get just null bytes back, though it does appear to be transmitting them.

[go4retro]

When I boot the Arduino and direct mine to COM3 (USB) 300,8,n,1, and reset, it spits out:

TestSerial Version: 0.1.0.0PR

Okay, then there's something really wrong. At 300bps I can see it sending stuff at reset but it's all nonsense characters. I'll have to mess with it some more.
