Hi,
I tried booting the STM32F103C8T6 via UART following the boot configuration details from the AN2606 document provided by ST. I have outlined the configuration below.
After setting up the boot configuration, I attempted to connect the STM32's UART using a TTL converter and the STM32CubeProgrammer software (Win64, versions 2.18.0 and 2.5.0). However, I encountered some issues, and I have attached a snippet showing the error.
I also tried connecting an STM32L562E-DK board, but I faced similar issues.
Could anyone help identify what might be going wrong? Your suggestions and advice would be greatly appreciated!
Thank you!
Hi,
Thank you for your response. Here are the details regarding your queries:
1. TTL Converter:
The TTL converter is working correctly. Before attempting the boot method, I verified its functionality by running a UART communication test application. The test confirmed that the TTL converter is operating without any issues.
2. Boot Configuration:
I followed the bootloader configuration details for STM32F103C8T6 as outlined in the AN2606 document, specifically under the STM32F10xxx devices section. I used Pattern 1 for the boot configuration. Below are the steps and connections I made:
Boot Pin Setup:
I set the boot pins as follows:
BOOT0: High
BOOT1: Low
Refer to the attached image for the configuration.
boot pin setup:
and after TTL side setup as mentioned Bootloader configuration :
TTL Side Setup:
Following the bootloader configuration guidelines, I connected the TTL converter's TX and RX lines as follows:
TTL TX -> STM32 USART1 RX (PA10)
TTL RX -> STM32 USART1 TX (PA9)
After this setup, I sent the 0x7F command to initiate communication but did not receive any response. Additionally, I could not establish a connection using the STM32CubeProgrammer software.
Refer to the attached images for further details.
Let me know if you need more details or if there are additional steps I should try. Thank you!
