Contribution description
This PR pins the installation of the
esptool.py
Python package to version 4.9.0 also for flashing.A couple of days ago, Espressif released version 5.0.0 of
esptool.py
and uploaded the corresponding Python package. Whileesptool.py
installation was pinned to versionv4.9.0
for compilation by PR #21588,esptool.py
versionv5.0.0
is still used for flashing. As a result,esptools.py
is installed again and again alternating betweenv4.9.0
andv5.0.0
.This PR fixes this problem.
Testing procedure

Without the PR,
epstool.py
is installed again and again and theflash
target throws a number of deprecation warnings. With the PResptool.py
is installed only once, the first time it is needed.Issues/PRs references
