partition table #4

Open FransM opened 4 months ago

FransM commented 4 months ago

There is an issue with the partition table. If I run ./rebuild-esp32s3-linux-wifi.sh the resulting image cannot be flashed due to the size of the xipImage Also the wiki mentions parttool.py write_partition --partition-name etc --input build-buildroot-esp32s3/images/etc.jffs2 but there is no etc in the partition table.

I'm having an S3 N16R8 device

but there is no etc in the partition table.

There is, but both issues suggest that you may not have it flashed on the device. Can you check that?

Maybe I goofed wrt the etc partition.

If I recall correctly I initially could not flash the partitions and then wanted to write the partitions through the command line, using the commands given on the wiki. For the s3 wifi version this resulted in a message that the xipImage was too big. The rootfs could be flashed and for etc it complained that there was no partition for it.

A later experiment with a clean rebuild did flash properly. Maybe the individual commands on the wiki are outdated, but it could also be user error ....

Sure, they're more of a general direction outline, the scripts should do the job precisely.

The issue is that the script does a full clean build including checking out all gits, building gcc etc etc. This is a bit time consuming. It is useful to have the individual steps if one e.g. wants to change the kernel config.

Take a look at the head of the script, there's a few environment variables that control what parts are downloaded/built. e.g. running keep_toolchain=y ./rebuild... will avoid downloading/building the toolchain.
