Hello,Stefan Thanks for your effort! I have followed your advice to check to genode 18.08. I used the patch you provided to me: https://github.com/skalk/genode/tree/imx53-hf-neon At first, I just build the whole project as before. But there's an error at building stage: can't read "cc_arch": no such variable
while executing "exec [cross_dev_prefix]gcc -print-libgcc-file-name {*}$cc_arch" (procedure "build_core" line 8) invoked from within
Then, I add the "cc_arch" to the file: ./tool/run/run, like this: set asm_src [generate_boot_modules_asm [run_dir]/genode $modules]
- set cc_arch "-mfloat-abi=hard -mfpu=neon"
# determine the libgcc set libgcc [exec [cross_dev_prefix]gcc -print-libgcc-file-name {*}$cc_arch]
After this, I can build the whole project successfully and measure the performance gain on the i.mx53 qsb board. However, there's still a problem. When my program have done and return to normal world, the system seems stuck. From the serial port, I can only see the linux's cursor blinking but I couldn't input any command.The serial port's output message like this: [init -> tz_vmm] task finished in 14588ms / #
There are no errors which just like a command have executed normally. Do you have any idea about this? Thank you very much.
Just out of curiousity, are you still using the tz_vmm.run script? And if so, did you changed it to do: "run_genode_until forever", or does it still use "run_genode_until <some_condition> <timeout>"?
regards stefan
