I have a J-Link Eclipse plug-in, I'm quite happy with Segger GDB support, and I would like a similar functionality from the emulator. as for the semihosting support, if I try to use it, I get: qemu: Unsupported SemiHosting SWI 0x00 R00=00000000 R01=00000000 R02=00000000 R03=00000000 R04=00000000 R05=00000000 R06=00000000 R07=200ffed8 R08=00000000 R09=00000000 R10=00000000 R11=00000000 R12=00000000 R13=200ffed8 R14=000022c5 R15=0000157c PSR=60000173 -ZC- T svc32 Abort trap: 6 if I try to use the Bechus branch, it (more or less) works, but not while the GDB session is active, which is a limitation. I'd also consider adding some tracing support (ITM, data tracing), etc, but I'm not sure this is reasonable with the current code. regards, Liviu
