Hi,

The TOOL variables were indeed set. I unset them and ran the source command and they returned to the same values:

OCPI_TOOL_OS=linux
OCPI_TOOL_PLATFORM=ubuntu22_04
OCPI_TOOL_ARCH=x86_64
OCPI_TOOL_DIR=ubuntu22_04
OCPI_TOOL_OS_VERSION=u22_04
OCPI_TOOL_PLATFORM_DIR=/home/dwp/git/opencpi/project-registry/ocpi.core/exports/rcc/platforms/ubuntu22_04

Running the source command also removed the TARGET variables and the problem returned when attempting ocpidev run
application example_rxToFile giving the following output:

/bin/bash: line 1: target-/example_rxToFile: No such file or directory
make: *** [/home/dwp/git/opencpi/cdk/include/application.mk:70: run] Error 127

It is only when OCPI_TARGET_DIR is set to ubuntu_22_04 that the application runs. I can see that this variable is used in the file
<opencpi-root-dir>/cdk/include/application.mk on line 63.

Thanks,
Dan
