Where have you added the writelist ? This is a feature in U-Boot and must belong to "uboot" section.
The error says that the format of fw_env.config is wrong and cannot be parsed.
Thanks for your reply.
I added it in the uboot section like this:
uboot:
size : 0x20000
lockfile : /var/lock/fw_printenv.lock
writelist:
- var1:so
- var2:so
- var3:do
devices:
- path : /dev/mmcblk1boot0
offset : 0x1000000
- path : /dev/mmcblk1boot1
offset : 0x1000000
swupdate:
size : 0x4000
lockfile : /var/lock/swupdate.lock
devices:
- path : /dev/mmcblk1boot0
offset : 0x1200000
- path : /dev/mmcblk1boot1
offset : 0x1200000
This is similar to how it is done in the documentation and should be normal yaml syntax
I have tested with current master and I cannot reproduce the issue. Anyway, writelist is supported only in -master, 0.3.5 does not contain commit commit 6b1c689 for writelist support. Please test with current master.
Thanks for your reply,
indeed, the meta-swupdate layer pulls the 3f4d15e36ceb58085b08dd13f3f2788e9299877b commit which does not include the commit required for writelist to work. I just tried with the current master and it works. Thanks for the heads up.
I experimented a bit with the functionality and it seems the o (write once) flag is treated the same as the r (read only) flag, even if the variable does not exist yet. Not sure if this is intentional.
Hi,
I have a fw_env.config file in YAML format on my device that looks like this:
With this config fw_printenv works without problem and prints all variables.
As soon as I add a writelist sequence like this
anywhere in the file I only get the output "Cannot initialize environment".
I am on version 0.3.5 773.
