Hi! My name ist Stefan, i like to upgrade my Jornada 720 to 128MB RAM. I soldered two Samsung K4S511632C-KC75 RAM Chips instead oft the two old 16MB ones on to the RAM/ROM board. So the hardware part is done, the J720 boots fine into WinCE and with the hpcboot.exe into NetBSD. But as expected only with 32MB available. I discovered that i can use the JORNADA728 kernel config file with - options DRAM_PAGES=16384, to get 64MB shown in NetBSD and everything is fine. But if I set this value to 32768 NetBSD wont boot. With - options DRAM_PAGES=24576 NetBSD boots, but stops with „panic: ubc_init: failed to map ubc_object“ - dmesg shows 98304KB total memory. Is anybody out there who can help me with this issue?
