I can't find the point of problem. Can you try next build with 4IN1_FLASH support disabled, but by different way. It will help localize the problem.

* Disable 4IN1_FLASH support by undefined HAS_4IN1_FLASH variable.

Hi vlad_vy, I'm currently testing build 2018-03-14 to see if this fixes the Missing Modules CRF6936 message.

vlad_vy quote: "Changes:
* Enable 4IN1_FLASH support, to check if it is the reason for "Missing Modules: CRF6936" message."

The problem is now fixed.

Many Thanks, Regards, Stefan

OK, I will enable 4in1 flash support to check if it is the reason. It it will work then 4IN1_FLASH support has error.

Since iRangeX iRX-IR8M (t8sg-v5.x.x-2017-09-19) is somewhat different from Jumper T8SG I will place here the builds for iRangeX iRX-IR8M.


Changes:
* Enable 4IN1_FLASH support, to fix "Missing Modules: CRF6936" message.

iRangeX iRX-IR8M based on Nightly Builds:

File deleted, see below...

Build 2018-01-31 is working fine
Build 2018-02-14 Missing Modules: CRF6936
Build 2018-02-22 Missing Modules: CRF6936

This problem isn't a filesystem problem I think you might have misunderstood my original post. The last two builds that follow 2018-01-31 are the ones that produce the Missing Modules issue. I have tried to upgrade to these numerous times I get the Missing Modules issue but as soon as I revert back to 2018-01-31 no CRF6936 issue.

The CRF6936 issue only occurs for me when the TX has been switched off for 2mins or longer in Builds 2018-02-14 and 2018-02-22.

2018-01-31 WORKS.

Build 2018-01-31 change is common for all transmitters, and other users havn't problems, so it's not a source of problem. I think it is filesystem problem, try to format transmitter USB drive, write filesystem and use "Safely Remove Hardware". Probably it can be a problem with I8RM hardware, this error has place with I8RM transmitters only.

For example, Jumper T8SG has 100% the same code, except one LCD setting and two channels reversed, but has not any I8RM problems.

Build 2018-02-21
I'm getting Missing Modules: CRF6936 when first starting the TX after it has been powered off for a couple of minutes. I power the TX off again wait for about 20 seconds power back on and then the TX behaves OK until the next time? In further testing, I found that the "Missing Modules" issue only occurs after build 2018-01-31.

Kind Regards, Stefan

My iRX - IR 8M was revived. Thank you very much.

Format transmitter USB drive and copy filesystem from firmware archive:
www.deviationtx.com/forum/builds/7605-ir...uilds?start=20#67668

My iRX-IR8M suddenly displayed the USB logo and it stopped working. Whichever button I press does not respond. Upload VIDEO. Can anyone tell me how to recover?

Hi.

I connected the trainer port and tried to connect the vibration motor.
Fortunately, it was successful.

This unit has a universal vibration motor hole. But I had to make a separate case to connect the remaining motor.
I can not understand why these things were not installed from the beginning
I can not trust this device.

I tested with two frsky receivers D8RII and D8RXP. At 100uW I achieve 50m without problems, It can reach 60m I believe....
At 150mW it is 1500x bigger than 100uW so theoretically distance will increase by 38x given to us ~1,9km. But again, theoretically.

Bonjour tout le monde je vien faire la mis à jour et il affiche sa il un solution merci

The iRangeX iRX-IR8M failure is now complete. The hardware design, manufacture, distribution and service was not up to the lowest basic requirements and expectations of an RC community that has been around for more than 50 years. Banggood's failure to openly acknowledge the concerns of it's customers and actively suppressing negative comments on their website sends a clear message, you can't trust them to do the right thing for customers.

I sent my TX back to banggood. Banggood will reimburse me for the cost of the shipment and the purchase price.

Guys, but have you done range tests? With the NRF24L01 module I have 1/3 compared to my I have 10 and with the protocols Dsm is something ridiculous ... Worse than I have 7. Without long range mod. Do yours go better?

If you update the firmware and get error on startup: "Missing modules: A7105 ..." or something similar => Most likely it is filesystem problem. Try to format transmitter USB drive, copy filesystem and use "Safely Remove Hardware".

Probably something is wrong with filesystem. Try to format USB drive, write filesystem and use "Safely Remove Hardware".

it gets weirder... After I started the TX in USB mode to copy the file and also opened it to check the contents, the error is gone, startup is normal now???

It's standard "hardware.ini". It doesn't help to understand why after installing latest software it says CYRF6936 chip is missing.

If you mean before update, no. This is the one I have now
