For Sigma EM8622 devices, your makefile should have produced a
"tftpd.gdb" and a "tftpd" file, and you are attempting to execute the
"tftpd.gdb" file.

tftpd is the bFLT ("flat") file, and tftpd.gdb is the ELF file.

When you try to run an ELF file on that device, it gives the above
error message.

So it looks like the wrong file was copied to your device, or the
makefile is not running compiling properly.

When compiling, it must have the option -Wl,-elf2flt=-s32768 or
something like that.
