Update: I realized that the commands I used above are specific to the libopencm3 examples. Here is the somewhat lengthy output of

I have added the STM32L011 but not 100% tested (only tested probe). Probably the configuration is broken (needs to verified against datasheet which I did not yet): See also: https://github.com/pavelrevak/pystlink/blob/master/lib/stm32devices.py#L82-L92 |

Thanks @xor-gate. I double-checked the
However after rebuilding I still got the same error. I'll keep looking into the issue. |

Ping @gluedig, @mcoquelin-stm32 could you verify this (if you have a target?). I'm not familiar with the current flash loaders. |
|
Probably @tomdeboer has also some thoughts as he had some commit history on the L0 flash loaders. |

Okay, I think I've got a fix for this. In common.h, there are a number of |

Thanks, feel free to open a new issue or PR when something is not working as expected. Thank you for your contribution! |

I am attempting to flash a simple 'hello-world' type LED blink program onto a bodged together STM32L011G4-based board, using my STM32F030 Discovery Board's on-board Stlink/v2.
Command:
$ make helloworld.stlink-flashOutput:

st-utiland uploading the file manually. One thing I did notice -- when I first attempted to flash the chip the SRAM size was set to 0x4000 (i.e. 16 KiB); this was incorrect for the STM32L0 I am using so I changed line 455 ofchipid.cto.sram_size = 0x800,and rebuilt the program. The flash memory size is correct for the G4 version.I tried running
st-flash eraseand it seemed to work fine -- all 128 pages erased. I also tried shorting the BOOT0 pin (pin 1) to VCC and resetting the chip a few times, as suggested by other users experiencing similar-looking problems. This didn't seem to have any effect on subsequent programming attempts.Perusing
common.cI did notice the following lines (ln 1835-1836):else if (sl->flash_type == STLINK_FLASH_TYPE_L0) {/* use fast word write. todo: half page. */Does this mean that the half page write mode isn't implemented and I just need to switch over to programming by word? I looked around for an option to do this but I couldn't find one.
