Hello,

my real Chip is a STM32L011F4, but it isn´t in the list.
So i select a STM32L011E4, should be the same memory map, only in an other package, with more pins.

In the "Select device" dialog it is said:
Flash Size: 16KB + 2KB + 32Bytes
RAM: 8KB

On the flash tab the sectors a described:
131 Sectors, 3 Ranges:
0x08000000 - 0x08003FFF (16KB of flash)
0x08080000 - 0x080807FF (2KB of EEPROM)
0x1FF80000 - 0x1FF8001F (32B of option bytes)

According to ST the chip should have:
Flash Size: 16KB (Flash) + 512Bytes (EEPROM) + 32Bytes (option bytes)
RAM: 2KB

out of the ST data sheet, i get this information:
0x08000000 - 0x08003FFF (16KB of flash)
0x08080000 - 0x080801FF (512B of Data EEPROM)
0x1FF80000 - 0x1FF8001F (32B of option bytes, but only 20 of them are really usefull)


And whe i try to do a chip erase, i get an error when trying to erase the 2KB of EEPROM, probably baceause there are only 512 bytes in the chip.

I can change the RAM to 2KB on the MCU Tab, then the RAM error is gone, but still noch chip erase is possible.

When i deselect the sector 128 (0x08080000-0x080807FF) and do a "erase sectors", it works.

So can you please have a look into this, and add correct support for the STM32L011F4.
Thanks.

Hi Fleshet,

yes, this works for me. I don´t need the EEPROM at the moment, perhaps later.

Thanks
