Hi ST ,
I have 100 qty of STM32L4R5VG with bootloader version 9.2 which is fault bootloader .
AN2606 says that the bootloader version 9.2 has a trouble with system reset repeatably so can not be used for bootloader.
I tried to fix this issue by myself, but I found there is no solution from this Q&A : https://community.st.com/s/question/0D50X0000BTbseCSQR/stm32l4r5vg-bootloader-version-92-not-working-only-system-reset-repeatably
How can I exchange the fault STM32L4R5VG with normal bootloader V9.4 or STM32L4R5VI ?
What's the process to exchange ?
Solved! Go to Solution.

Contact a ST sales representative, FAE or distributor.
I'm pretty sure they don't discuss it on a public forum.

Today, I call with the sales representative , they say "we can not exchange, we are not responsible to you and you should request that mouser you purchased..". That's all.
What ? ST peoples are all insane?
Bootloader trouble is caused by ST's fault manufacturing and quality process.
ST must resolve this issue responsibly !

Most people on this forum are users of their products, and not affiliated with ST. And a few technical ST staff.
Meaning, you can't expect much help in legal issues here.
Perhaps escalating inside your company (project management, purchasing department, if any).

Thanks Ozone.
Now, I see there is "a few technical ST staff" in this forum. I think I get it now.
OK I will take a different route.
