I asked this question in another forum, but should have asked it here, sorry for asking again.
u-boot.2013.07 build configured using mx28evk_config fails with serial_puts() undefined if I add debug() or serial_puts() calls to the source for debugging purposes.
I didn't have this issue with u-boot.2013.01 .
Do I need to #define something to include serial_puts() ?
I tried adding #define DEBUG to include/common.h but still get build errors.
Thanks for any help,
Ok, this was my mistake.
CONFIG_SPL_SERIAL_SUPPORT needs to be defined.
I had in fact modified the u-boot-2013.01 board config file to include this to get it working before.
