mobula7 betaflight update issues

mobula7 betaflight update issues.md

I'm running into similar issues trying to update my Mobula7 from Betaflight 4.3.1 to 4.4.2 also using a Radiomaster Zorro. My original diff all and after update diff all are quite different and restoring mostly complains about the following:

# resource PPM 1 A03
###ERROR IN resource: INVALID RESOURCE NAME: 'PPM'###
# resource PWM 1 A02
###ERROR IN resource: INVALID RESOURCE NAME: 'PWM'###
# resource PWM 2 A09

###ERROR IN set: INVALID NAME: name = Mobula7_1S###

# set anti_gravity_gain = 4500
###ERROR IN set: INVALID VALUE###
Allowed range: 0 - 250

1. What do the PPM/PWM resource errors mean and are they safe to omit?
2. All osd_* errors seem like they're related, any did I miss somrthing when building the firmware?
3. Setting name seems like it should work, what's up with this?
4. anti_gravity_gain value seems normal and I didn't see any changes to this param recently, could this be a betaflight bug?

I also did a partial diff when I got it but I don't think that's as useful as the full one.

UPDATES:

• OSD issues seem to be related to betaflight/betaflight#11671 where all the osd_warn_* and osd_stat_* were changed to use bitmasks. Generating the bitmasks using old values is a huge mystery to me. Maybe available via UI in BF? betaflight/betaflight-configurator#3256 (comment)
• The config name was changed to craft_name in betaflight/betaflight#11391
• Anti Gravity stuff changed in betaflight/betaflight#11679, default value is supposed to be 80, maybe 4500 can be converted to 45? Will remove from config and see what happens.
