Enabling CYGHWR_THUMB should be sufficient. Be sure to "make clean" when
switching to Thumb. Also, check that the -mthumb and -mthumb-interwork
flags are definitely present during the building of your eCos tests.

I have just verified that the kernel tm_basic test builds for target
eb40a (ARM7) with RAM startup and CYGHWR_THUMB. The resulting binary
runs under debug (via RedBoot) without problem. This is using the new
eCos 4.6.2-20120125 test release toolchain.
There could be a Thumb-related issue within a certain variant/platform
HAL or device driver package.
