I noticed what I believe is an error in UG1144 for v2019.2
On page 121 under the section "Creating and Adding Patches For Software Components within a PetaLinux Project" step #7 reads:
"Once you have finished working on the recipe, run devtool reset <recipe-name>. It will remove the source directory for the recipe from workspace."
I believe the correct PetaLinux command which invokes the underlying devtool command is actually:
petalinux-build -c <recipe-name> -x reset
It looks like this was also copied into v2020.1 as well on page 146
Devtool could be used directly as described in v2020.1, however the flow of the steps that lead to the command above is not the same workflow.
You are right. That is how it should be invoked. It is listed correctly on Table 9 (v2020.1) but got missed on page 146. Will report this to the doc team. Thanks
