--- **[tickets:#402] STM32L43x Option Byte read/write error** **Status:** new **Milestone:** 0.10.0 **Created:** Tue Jun 20, 2023 09:34 AM UTC by Arney Sieling **Last Updated:** Tue Jun 20, 2023 09:34 AM UTC **Owner:** nobody `stm32l4x option_read` and `stm32l4x option_write` uses incorrect base address (or at least for the STM32L43x family of MCUs, I did not verify the Option Byte addresses of other STM32L4x MCUs). The base address currently used by OpenOCD for STM32L4x MCUs is `0x40022000`, this should be `0x1FFF7800`, and as a result any calls to `stm32l4x option_read` and `stm32l4x option_write` fails to read/write the option bytes of an STM32L43x MCU. --- Sent from sourceforge.net because openocd-devel@lists.sourceforge.net is subscribed to https://sourceforge.net/p/openocd/tickets/ To unsubscribe from further messages, a project admin can change settings at https://sourceforge.net/p/openocd/admin/tickets/options.
