STM32G030 datasheet indicates BOOT0 is PA14-BOOT0 and that SWDIO is PA13 and SWDCLK is PA14-BOOT0.Upon power up, how does the STM32G030 know whether PA14-BOOT0 is controlling whether to enter bootloader mode or is SWDCLK?Since STM32G030 has no JTAG c...

Have STM32G030K6T6 system that in bootloader mode fails to respond to I2C.Am asserting BOOT0 pin 25, negating NRST pin 6, wait 500ms, asserting NRST pin 6, wait three seconds, then attempt to send MCU erase packet to I2C1 device address 0x56 but get ...

STM offers a utility to convert an ST-LINK debugger to J-LINK debugger.USB drivers are current.But when "stlinkreflash.exe" is run [in admin mode], it says "cannot find an ST-LINK, multiple ST-LINKs are plugged in, or ST-LINK in use".None of that is ...

The STM provided USB host project has the following readme text:- STM32H7B3I-EVAL Set-up - Plug the USB key into the STM32H7B3I-EVAL board through 'USB micro A-Male to A-Female' cable to the connector: - CN8 : to use USB High speed (HS), Make sure...

Aime:Many thanks for your information.However, please clarify, what combination of PA14_BOOT0 pin and option bits BOOT_LOCK, nBOOT1, nBOOT_SEL and nBOOT0 starts the STM32G030 MCU bootloader, that then allows I2C to burn user flash memory?And with tha...

I presently have a EE wiring up an SWD connection to the STM32G030.With that, I presume I will be able to use STMCubeProgrammer to both burn user firmware and diddle MCU option bits.However, it is still not clear to me how PA14_BOOT0 manages to serve...

I realize that AN2606 4.1 Bootloader Activation Table 2 defines various bootloader activation patterns, and what you describe above appears to be one of the Pattern 11 sequences but I cannot find documentation describing how to control nBoot1(bit) an...

"Is this happening on your STM32H7B3I as well? (But recoverable via SWD/JTAG?)"Yes, but only when I botch something, e.g., leave Segger running on the secondary STM32H7B3I then simultaneously try to reboot the MCU and send bootloader messages."Perhap...

The EE quit.The EE's boss is now doing the EE.He told me he may be able to jury rig a J-tag connection.Background:The mother board has two STM32H7B3I, a MAIN and a FrontPanelController [slave via I2C].The code I wrote for MAIN can reliably burn the F...
