Program update

[GauravK]

Hi,

1. is there any tool (GUI) to update program using executable?

2. How to have different modes of programming? (UART/ USB/ sd card)

3. Bootloader mentions: USB OTG FS (PA11/12) in Device mode (DFU: device firmware upgrade). Can external HS phy in FS as a device be used to update program?

Hello,

1. is there any tool (GUI) to update program using executable?

Using STM32CubeProgrammer tool

2. How to have different modes of programming? (UART/ USB/ sd card)

---

Read AN2606 STM32 microcontroller system memory boot mode / Read the table " configuration in system memory boot mode" that corresponds to your device. It describes the different resources and which interface is used for bootloader for that device. SD card is not a part of the ST bootloader you need to develop it yourself.

Same answer as 2.

Hi, reading on program update is ongoing.

I tried using STM32CubeProgrammer and was able to program using ST-Link. 

but I tried USB FS device with DFU, and STM32CubeProgrammer was able to detect USB and when connect is pressed...the bottom bar keeps on searching and never finishes...this is with STM32F469 discovery kit.

I tried loading "DFU_standalone" also but could see same.

Please any suggestions?

What about boot pin? How you did manage it? & Reset?

[GauravK]

on kit I see boot 0 and boot 1 are to GND through resistors, I was not able to change those.

Also I tried pressing RESET button, nothing happened

I didn't go for having USB FS connected and re-plugging ST-Link cable, since I read board should be powered before connecting USB.

Reading is on-going, if any suggestions from experts, can speed-up our understanding

The features and functions of the ROM will be limited. It's aimed at production programing or debricking in the field. 

For a better, more tailored, user experience you code your own loader with the rich features you want. One that implements DFU, or MSC for a drag-n-drop update, does serial XMODEM from a terminal app, or checks an SD Card for an update image.

I changed Boot0 to 3.3V and was able to do "Start Program" from CubeProgrammer, USB was detected and download looked complete. But it didn't boot to flash.

So changed again boot0 to GND, but don't see the program updated...

Is anything missed?

I used .elf files, 2 numbers, both having different LEDs to be toggled

Did you reset the MCU after changing boot0 to GND?

[GauravK]

yes reset press tried, also USB cable re-insertion tried.
