Mity CPU Platforms » MityDSP-L138 (ARM9 Based Platforms)

Tom,

For following the Wiki, the "Release 2014.01" MDK is the best choice right now. The Wiki documentation has not been updated to match the newest MDK releases (e.g. Release 2017.08 - BETA).

After you work through some examples with the older MDK, you can try the newer MDKs and if you have any questions, you can post them here.

If you are familiar with embedded Linux, however, you shouldn't have too many problems with using "Release 2017.08 BETA."

Here are the main differences with the new tool chain:

• First, the environment setup script has a different name:
  

   # source /opt/criticallink/mityomapl138_20170818/environment-setup-arm926ejste-criticallink-linux-gnueabi
  

• Also, if you are compiling the kernel, before you run any of the make commands, please reset your LDFLAGS variables (otherwise you will get strange ld-related errors).
  

   # export LDFLAGS="" 
  

• Finally, you will need to change any CROSS_COMPILE prefixes to match the new binary names in the newer MDKs. For example:
  

  # make -j4 ARCH=arm CROSS_COMPILE=arm-criticallink-linux-gnueabi-"

Bob... sounds good thanks, Tom
