Hi Tom, Thank you for the patch.

Looking at drivers/dfu/dfu_alt.c both dfu_write_by_name() and dfu_write_by_alt() seem to rely on functions from drivers/dfu/dfu.c such as dfu_init_env_entities(), dfu_get_entity() and more. Looking at UPDATE_COMMON, I see: config UPDATE_COMMON bool select DFU_WRITE_ALT imply CMD_TFTPBOOT And if we check the code in common/update.c, we can see that dfu_write_by_name() is called. So fit_update() calls dfu_write_by_name() which calls dfu_init_env_entities() which might no longer be defined when applying this patch. I'm not sure how is this supposed to work. Do we have to stub dfu_init_env_entities() ? > > Signed-off-by: Tom Rini <[email protected]> > --- > Cc: Lukasz Majewski <[email protected]> > Cc: Mattijs Korpershoek <[email protected]> > Cc: Heinrich Schuchardt <[email protected]> > Cc: Ilias Apalodimas <[email protected]> > --- > drivers/dfu/Kconfig | 2 +- > 1 file changed, 1 insertion(+), 1 deletion(-) > > diff --git a/drivers/dfu/Kconfig b/drivers/dfu/Kconfig > index 2cf4289b4486..962bda40ad2d 100644 > --- a/drivers/dfu/Kconfig > +++ b/drivers/dfu/Kconfig > @@ -13,10 +13,10 @@ config DFU_OVER_TFTP > bool > depends on NET > > -if DFU > config DFU_WRITE_ALT > bool > > +if DFU > config DFU_TFTP > bool "DFU via TFTP" > depends on NETDEVICES > -- > 2.43.0
