android.exe improvements

[Jamey Hicks]

If you update connectal from git or install the latest package (v15.03.12) you will need to update boot.bin to zynq-boot version v15.03.8 or newer. Prebuilt images are available here:

I made several changes to zynq-boot, fpgajtag, and run.android so that run.android can run the application as the default non-root user.

Summarizing some of the recent changes:

• programmable logic is packaged in android.exe
• android.exe invokes fpgajtag to program the logic
• fpgajtag is now setuid root, so that it can access /dev/xdevcfg
• fpgajtag is now located in /fpgajtag (part of boot.bin) because /mnt/sdcard is vfat/msdos and does not support setuid bit
• as part of cleanup, init process loads modules portalmem.ko and zynqportal.ko
• this removes several steps from run.android

If you run the application on a zynq board manually, the only thing you need to do is invoke android.exe. It will automatically program the logic using the attached bitstream. I am very happy that we eliminated all the extra steps that used to be required.

Cheers,
