Should be easy to find the correct one on ebay or such.

thanks for answer.So how is stm32f207VET6 ? it availble from store near my house

hi all
i had taranis x7 problem a OUPUT volt for modul. i checked and detect pin ON/off power for modul on stm32 is dead. So i can replace a STM32 other , but i only can buy a stm32f205VCT6 is not VET6 . So it can work ?
thanks

It worked , it worked

Thank you so much MIKE , you are right . Crystal is cause for all problems
crystal come soon to day. i replaced it and it can run both file ersky and opentx taranis .

now my taranis worked back .

hi Mike
i orderd a new crystal and it will come in next week.
i will report result here

measure batterry is 3v

i have not yet replace a Stm32f205. can not buy a new chip now .But i can buy a STM32F207VET6 or STM32F407VET6 now , so i can replace stm32f205 by stm32f207 OR 407 ?

video tested ";https://www.youtube.com/watch?v=NU9-T0oMaq8

i flashed firmware .

I saw corner display P , after go to SWITH WArrning , screen blink same file ersky9x ago.

moved all Stick , switch ....

eeprom maybe not issue. I removed Eeprom again by hot air. then power on tx . Ersky9x.bin on Taranis x9d also can not work.always Reset when go to eeprom formating . i soldered EEPROM ahain and it can pass check EEPROM . HMMMMMMMMM now only STM32f205 ???? what are you do now ? U4 : what is feature ?...

yes , i read model , wrote model on companion ok.
i also check power 3v3 , it stable .

ok . let me know if you complete

mike

Can you write a firmware do not use EEPROM (m24256 ) for ERSkY9X on taranis ?

hello MIKE and Kilrah

I flashed direct by STLINK usb. but it not change . Same Problems ago

idk beside STM32F2 , any component affact to tx stop down ?

yes Mike ,Kirah
that is all problem

connect is Ok . i borrow a TX from your friend to check

in companion , i still can read MODEL, write model OK

nothing is mean Stop down.
still display CONVERTING or FOMARTING. Have to remove battery

i fashed right all firmware for taranis plus .Even frimware orginal You said hardware problem , but i saw TX alsmost only stm32f2.Other components are just minor. So any cause about hardware do it not work ? Even i replaced a EEPROM m24256 , Sd card but not change about EEPROM I saw on screen EEPROM...

hi Kilra
After i flashed so much version Companion OPENTX , My TX still not work. So i think i will erase chip STM32F2 by stlink and then flash firmware again.

but i wonder after erase chip STM32 , it will lost mode bootloader

hi

after you replace new stm32 , Only plug usb to PC , it will note a STM32 bootloader ? Do not need use a Stlink usb to flash ?

hello mnementh

how to flash firmware for Stm32f2 ? You use a stlink ? and where is firmware ?

i have a big problem with taranis and have flash again firmware for stm32f2
