Oh, no the segfault happened when using qemu/serialice v1.5 and is solved using qemu from svn, on 32-bit hardware too.
In my previous message I forgot to attach the superiotool dump -- see attached file.
Following quote is after soft reset, typing some text and hitting the reset button:
Since the southbridge and superio datasheets mention the existence of two serial ports, I followed their guidance.
thought that (the console printing part of) SerialICE, when setup the
correct way, should survive a hard reset/power cycle regardless of the
qemu part is running or not.
Since I don't have an oscilloscope, I've tried setting CLKSEL to 24 MHz and 48 MHz:
CONFIG_PORT, 0x24, 0xb4); // 24 MHz and KBC=1
pnp_write_register(SUPERIO_CONFIG_PORT, 0x24, 0xc4); // 48 MHz and KBC=1
What information is leading, the info from the superio or the info from the southbridge ?
