#173 STM32U0 Support - Unknown/unsupported device (Device ID: 0x489)

[Samuel Lückoff]

With the stm32u073cct6, I get the following error message:
stm32flash 0.7

http://stm32flash.sourceforge.net/
Unknown/unsupported device (Device ID: 0x489)

Is it possible to support the STM32U0 MCU's?

It is possible that it just needs the right parameters in dev_table.c and it will work.

I have added placeholders for this device (and all other devices in latest AN2606) in dev_table.c, in hope that people will contribute the missing pieces, after looking up the individual data sheets and testing on their devices.

I would test it with the following line, if someone provide a binary to me:

/*  {0x489, "STM32U073xx/83xx"                , 0x20002170, 0x2000A000, 0x08000000, 0x08040000, 1, p_2k, 0x1FFF7800, 0x1FFF7860, 0x1FFF0000, 0x1FFF6800, 0}, */

Here the reference documents AN2606 rev 66
SRAM Table 209 STM32U073xx/83xx
System-mem-addr Table 192 26 Kbytes, starting from address 1FFF0000,

STM32U0 – FLASH Memory Flash presentation
Flash-Address: Main Memory Page 7
PSize: Page 7
Option Byte: Page Option Bytes are used to early configure the system-on-
chip before starting the Cortex®-M0+. They represent 96
Bytes.
Not complete sure but other Products with Coretex M0+ have also this rang: 0x1FFF7800, 0x1FFF787F

If someone can provide a binary with these configuration, I would test an upload over UART to STM32U073CCT6

Thanks! Here is binary with your patch.
