...y VDSP, so I can link. But this was useless anyway, as the calling conventions are different... Although uClinux is great and the GCC are very good tools, it's not an option for me, because I need: - a small RTOS, where I can control hardware directly, and the VDK is just fine - an IDE with JTAG debugging, and VDSP is good enough. But maybe I'm wrong and we can debug using Eclipse without the gdbserver running on the linux target ??? -- Stephane Lesage ATEIS International

...mpilation will produce binary files or equivalent file. But I fail to find it. Question: 1. How to build the binary files or equivalent file that can flash in the embedded device? 2. How to flash in the binary files or equivalent file into the embedded device? Can I do the normal flashing through JTAG tool? 3. How to configure /etc/samba/smb.conf at embedded device? FYI, there is many of embedded devices need to produce. Hope can hear from you soon. Thank you. Regards, Ang Hock Leong

Hi David, If cost is an issue then, yes you can do all that (the speex at least) with the eZDSP USB stick. Only limitation is a slow emulator that is integrated with USB, and so there is no JTAG output to use with other emulators. If you don't have an emulator anyway then this is an advantage.

...m what I understood, this tests run completely on the target (compilation of LLVM, unit tests, etc). So, for bare-metal tests that wouldn't work. We'd need to have a staging server that would compile to all platforms and run the tests (maybe just a subset) in the hardware via USB (mBeds) or JTAG on most other boards, or even better, on models directly. Do you think this is doable with the build bot infrastructure? cheers, --renato

Isn't this what Apple does with OpenGL, except that they skip the DLL step?
