Thank you, Nino. I am setting Option Bytes via software inside MCU with special command. Problem solved. Regards, Andrii.
Hello Nino, I do not set option bytes manually. I am using Secure chip functionality in the JFlash software, without any additional scripts: forum.segger.com/index.php/Att…26c8db7530cdede1da45b630b For some reason, when Secure chip is used with STM32L100R8/A MCU, option bytes become corrupted. Best regards, Andrii
Hello. I am observing strange Jflash behavior when using Secure Chip option. How to reproduce: 1. Connect to the target. 2. Perform Production Programming(erase, program, verify). 3. Check option bytes. I am using special software here. It reads option bytes and sends them via UART. Option Bytes values: 0xAA005500; 4. Perform "Secure Chip" operation. 5. Check option bytes. Option Bytes values: 0x0000FFFF; Option bytes are in Electrical Erase state? Chip is not secured, option bytes are't correct…
