Digi ESP for Embedded Linux
Version: 2.0 for Digi Embedded Linux 5.9.2.1
Build id: 20120709 DEL-5.9.2.1

platform: Wi-i.MX53

Answer 1

Digi provided Digi ESP for Embedded Linux which will select the cross compiler gcc tool depending on the platform.

ESP for 5.9.2 has support for ConnectCore Wi-i.mx53, ConnectCore Wi-i.mx51 and ConnectCard Wi-i.mx28.

i.mx53 and i.mx51 are Cortex A8 architectures , and so it will use arm-cortex_a8-linux-gnueabi

Answer 2

BTW, i just noticed that you have 5.9.2 which is real old and you cannot upgrade to latest pathces.

Download 5.9.3 from http://ftp1.digi.com/support/documentation/CC_i.MX53_Updates.htm and run package manager to upgrade to 5.9.6.2 which is the latest now.

Remember you cannot upgrade to 5.9.6.2 from 5.9.2 .
We need to have 5.9.3 to upgrade to 5.9.6.2.
