RTEMS on Zynq Microzed

[Davide Viti]

Hi Jeff,
I've tried the following steps:

 - cloned https://github.com/antmicro/zynq-mkbootimage.git
 - create a bif file with fsbl.elf, fpga.bit, u-boot.elf (tried both the
unstripped and stripped version of hello.exe)
 - I renamed hello.elf into u-boot.elf and created BOOT.BIN
 - copied BOOT.BIN to the fat partition of the microSD

Nothing comes out of the terminal window:I repeadetly see the blue led for
a short period (I think is indicating the bitstream being loaded), followed
by a shot blink of a red led.
Am I doing anything wrong?

thank you for your help,
Davide
