AN2606 missing STM32G4A1 series

[tizdipietro]

I'm trying to configure the Bootloader for a STM32G4A1KE processor, but in the AN2606  I cannot find any information regarding this processor (family STM32G41). Although it is listed in the introduction section of AN2606, no further information is given in the AN. Can someone point me out where I can find this information. (I am particularly interested in which UART can be used, which pins and which BOOT pattern has to be configured).

Hello @tizdipietro ,

The STM32G4A1 bootloader configuration is mentioned in AN2606Rev60 and precisely in Section "48 STM32G491xx/4A1xx devices bootloader".

The STM32G491xx/4A1xx bootloader is activated by applying Pattern 15.

You can use USART1(PA10 and PA9) or USART2 (PA3 and PA2). Note that USART3 isn't available for STM32G4A1KE MCUs devices.

Thank you.

I was searching for G4A1 and could thus not find it. Thanks for the fast reply
