STM32L011G4 flash error (unknown coreid, write_half_pages failed) #564
Description
- Programmer/board type: Stlink/v2-onboard (STM32F030 Discovery Board)
- Operating system: Linux Mint 17.2
- stlink version: v1.3.1/git-6f24bde
- stlink commandline tool name: st-flash
- Target chip: STM32L011G4
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-flash
Output:

I got the same error using st-util and 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 of chipid.c to .sram_size = 0x800, and rebuilt the program. The flash memory size is correct for the G4 version.
I tried running st-flash erase and 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.c I 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.
