you have a CI20? In http://openocd.zylin.com/4246 the question came up if the workarounds necessary for the JZ4730 are necessary also for later XBurst chips. > The cpu of the Letux400 is a bit hampered by the lack of the FPU > requiring a recompile - the original distribution from HongKong was > optimized for that and run fast - including a mini-Firefox and MP3 > playback working, instead on Debian which requires hard-float and > emulation is used, performances are bad, you cannot even an audio > file.

Before ARMv6 there were very few ARMs with fpu. The NXP LPC3250 is the only ARMv5 I know which has one. When I bought my Letux 400 we still had customers starting Linux projects on fpu-less ARMs. Best regards, Daniel _______________________________________________ OpenOCD-devel mailing list [email protected] https://lists.sourceforge.net/lists/listinfo/openocd-devel
