Question
STM32L07xx I2C BOOTLOADER. Write operation limited to half-page.
On a STM32L071 using preloaded bootloader enabled via BOOT0 lead, I can perform a write operation, but due to software constrain I cannot write more then 32 byte by time. So after a complete erase, I repeat several write operation, 4 for every page. Tprog time is respected.
Both write operations respond with a ACK signal. I notice that only the first operation succeed , the second one leave the rest of the half-page blank.
