No OSD on Cetus after FC Flash

[a-di-ez]

Hello,

After flash firmware on Cetus (Lite 1S Pro V1.1) I don't see any information (about fly time, mode, battery voltage) on the screen. There is only a raw view from the camera and word DISARM. Could you help me and tell me what I should do to enable this information - I don't see this option in BETAFPV Configurator (v1.1.0) Windows version.

Best regards, Vadim Osochenko

Hi Vadim,

did you try the solution from the task: https://github.com/BETAFPV/BETAFPV_Configurator/issues/7 ?

[a-di-ez]

Hi, @m4rc1no5 I don't have Cetus Pro, need OSD firmware for Cetus

[a-di-ez]

@HWT662988 any progress?

[HWT662988]

hi,a-di-ez I'm so sorry to see your issue so late, I need to ask which firmware is suitable, I'll tell you how to do in a minute

[a-di-ez]

cetus 1.0.1 from december 2021

[HWT662988]

hi,a-di-ez The Lite 1-2S Pro is the early alias of Cetus Pro, I need to know whether your FC's motor is brushed(cetus) or brushless(cetus pro)

[a-di-ez]

this is strange, because the board says: Lite 1S Pro V1.1 FC's motor is brushed(cetus)

[a-di-ez]

I can send photo of FC board

[a-di-ez]

[HWT662988]

OK,It is the early version ,and the baudrate between OSD and FC has been updated in later versions, here is early firmware the you can flash and test if it is available. Cetus_brush_2021-08-28.zip

[a-di-ez]

@HWT662988 OSD is back, but now there are even more problems:

1. I can't connect the drone to configurator for change rates - Need to update the firmware
2. After turning on the remote control, the drone starts flashing green and does not respond to commands

[HWT662988]

about the first problem I will tell you how to do later. and about the second problem: flashing green indicates your FC is in binding mode , you just need press the bind button on you LiteRadio to binding it.

[a-di-ez]

Can I revert to later firmware version now until you resolve my problem?

[a-di-ez]

I think this is not necessary, since my old rates were preserved after the firmware upgade, is this possible?

[HWT662988]

yes , upgrade firmware do not change the rates .

[a-di-ez]

great, wait on your solution!)

[HWT662988]

1.you need to erase the OSD 's firmeware by the old Cetus-configurator. Cetus-configure.zip

2.open the BETAFPV Configurator ,flash the new OSD firmware firstly. LiteSilverOSD_2021-10-26.zip

3.and then you can upgrade the new FC firmware .

[a-di-ez]

This checkboxes missed

[HWT662988]

check if here:

[HWT662988]

you just need to use the Cetus-Configurator to erase the OSD's firmware . and please do not use it to upgrade the firmware.

for upgrade the firmware you can use the BETAFPV Configurator because It can avoid some flashing mistakes on chip.

[a-di-ez]

I know, I'm go to SETUP from your first screen instructions

After click on Erase OSD btn - I don't have any results or messages Need erase in White LED color mode?

[HWT662988]

don't need erase in White LED color mode, It will not return message. you just need click on Erase OSD btn,and come back to BETAFPV Configurator to flash the new OSD firmware

[tano68]

hi, your answers in that thread is very helpful, so i would ask you something. I'looking for a working sensor firmware for the cetus pro. The latest version available im the github isn't recognized by Configurator (like the one for OSD). Do you have a link for it ? Thanks for your support.

[a-di-ez]

@tano68 create new issue please, your problem is not related to Cetus (Not PRO)

[a-di-ez]

@HWT662988 your solution doesn't work, any idea?

[HWT662988]

hi, a-di-ez please use this new configurator to erase the OSD 's firmeware. configure_V3.zip

.

please do not erase the other firmeware (Sensor and FC).

[HWT662988]

@tano68 hi,tano68 you can create a new issue for this problem.

For sensor firmware, It is not recommended to be updated, the factory firmware of sensor is the most suitable. and the latest version you saw just for compatibility with the changes of chip.

[a-di-ez]

@HWT662988 erased successfully, load Lite OSD successfully too, but OSD does't work(

[HWT662988]

please load and flash the OSD firmware again. use the BETAFPV Configurator. The osd firmware is named "LiteSilverOSD_2021-10-26" which and be download above. flashing OSD need be in the White LED color mode.

[a-di-ez]

It's strange that you tell me to flash in White LED color mode, because in another LED mode the firmware is impossible But I again flashed OSD in White LED color mode and of course no change in the end

[a-di-ez]

I found a solution, need to use Configurator V3 (configure_V3.zip above) with this firmware Cetus_brush_2021-08-28.zip In result I can change Rates and see OSD New Betafpv_Configurator v1.1.0 doesn't work with Cetus (Lite 1S Pro V1.1) or you last OSD after upgrading firmware
