Home Assistant wont start with 7.X.X firmware (ERROR_OUT_MEMORY, and RESET_ASSERT)

[xatr0z]

I'm not entirely sure if I have to report this here, at zigpy or home assistant, so sorry in advance if this is the wrong place. :)

I tried upgrading my Itead Zigbee stick (model without antenna/case) with the unsigned images.
ncp-uart-sw_v6.10.3_115200.gbl worked fine in HA, but didnt solve the bugs with aqara devices i am having. Therefore i tried ncp-uart-sw_7.0.2.0_115200.gbl and later ncp-uart-sw_7.1.1.0_115200.gbl . Flashing both went OK and device went back to normal mode. But I wasnt able to get it working in HA:

• [bellows.ezsp.protocol] Couldn't set EzspConfigId.CONFIG_MULTICAST_TABLE_SIZE=16 configuration value: EzspStatus.ERROR_OUT_OF_MEMORY
  • fixed that by forcing it to 12 (setting it to 16 had no effect) with: CONFIG_ADDRESS_TABLE_SIZE: 12
• after that the next error appears: Couldn't set EzspConfigId.CONFIG_TRUST_CENTER_ADDRESS_CACHE_SIZE=2 configuration value: EzspStatus.ERROR_OUT_OF_MEMORY
  • tried setting to 2 and 1, but would only start with 0: CONFIG_TRUST_CENTER_ADDRESS_CACHE_SIZE: 0
• Kept hitting different issues after that. So I tried different configs posted online:
  • From issue at itead

      CONFIG_APS_UNICAST_MESSAGE_COUNT: 32
      CONFIG_PACKET_BUFFER_COUNT:       250
      CONFIG_NEIGHBOR_TABLE_SIZE:       26
      CONFIG_SOURCE_ROUTE_TABLE_SIZE:   200
      CONFIG_ADDRESS_TABLE_SIZE:        14
    

  • Different variations ie

      CONFIG_APS_UNICAST_MESSAGE_COUNT: 32
      CONFIG_PACKET_BUFFER_COUNT:       250
      CONFIG_NEIGHBOR_TABLE_SIZE:       26
      CONFIG_SOURCE_ROUTE_TABLE_SIZE:   16
      CONFIG_ADDRESS_TABLE_SIZE:        12
      CONFIG_TRUST_CENTER_ADDRESS_CACHE_SIZE: 0
      CONFIG_MULTICAST_TABLE_SIZE:      12
    

  • As advised by puddly:

     CONFIG_ADDRESS_TABLE_SIZE:              16  # FW:  32, ZHA:  16
     CONFIG_MULTICAST_TABLE_SIZE:             8  # FW:   8, ZHA:  16
     CONFIG_PACKET_BUFFER_COUNT:            250  # FW: 250, ZHA: 255
     CONFIG_SOURCE_ROUTE_TABLE_SIZE:         16  # FW: 200, ZHA:  16
     CONFIG_TRUST_CENTER_ADDRESS_CACHE_SIZE:  2  # FW:   0, ZHA:   2
    

  • Based on values in the readme here:

      CONFIG_CTUNE_VALUE:   128
      CONFIG_ADDRESS_TABLE_SIZE:  32
    

...but none worked. I ended up with an unresponsive coordinator (RESET_ASSERT which i assume is some sort of crash):

2022-11-27 14:45:06.349 DEBUG (bellows.thread_0) [bellows.uart] Error code: RESET_ASSERT, Version: 2, frame: b'c2020682af7e'

This were the bellows defaults: bellows_defaults.txt

PS:
Eventually I tried to go back to 6.10.3 and encountered the same issue as #28 . The outlined steps (using onboard buttons) helped to be able to revert the firmware to ncp-uart-sw_v6.10.3_115200.gbl

This problem may be related to NVM cache, you can try to use nvm3_initfile.gbl file to reinitialize NVM.

May i requesting (not for my but for our users in the future) then making new EZSP firmware patching the 2 above configuration parameters (or using more standard settings the your chip have enough ram and CPU) so not getting problems with the coordinators.

One link for more information that can being good then some parameters cant being set in the GUI in SS5 NabuCasa/silabs-firmware#1 (comment).

Thanks for the reply, I already tried the nvm3_initfile but it didnt help

Set CONFIG_SUPPORTED_NETWORKS to 2 for the 7.x images from this repo.
Bellows wants to set this to 1 (lowering limits should always work). However, the firmware simply crashes.

If you want to go back to 6.x firmware, you need the init file.

(Both 7.x with the config and going back to 6.x with the init file worked for me)
