Thank you for your inquiry.
Which board are you trying to program?
Is it an eval board or custom hardware?
Which external Flash are you trying to program?
For the iMX2 series external Flash download is not supported by default.
J-Flash can currently only program a CFI compliant external Flash that has been configured by the user.
More information about this can be found in the J-Link user manual in section "Setup for various debuggers (CFI flash)".

If you are looking for a custom Flash loader for your setup our open Flash loader interface can be used:

Best regards,
