you should not have any issue if TrustZone is enabled and RDP is level 0. **but if the RDP is Level 0.5** the trick here is that the loader needs a place in the RAM to run, but since the system is secure and the RAM as well, we need either to specify the non-secure RAM as workarea (unknown to the debugger and the user has to provide it) or just disable the loader and do the programming without the loader.
I would recoment the easy way, so I instrumented the flash driver with a new command: `stm32l4x flashloader <num> [enable | disable]` `<num>` is flash bank number as shown by the command 'flash banks', in simple usecase, this should be equal to 0 you can add it to you configuration file, please let me know if this works for you. I will try to provide an intelligent way to enable disable the flashloader depending in the situtation in next week. --- ** [tickets:#319] stm32l5 flashing issue** **Status:** new **Milestone:** 0.11.0 **Labels:** stm32lx flash **Created:** Fri Sep 10, 2021 06:53 PM UTC by Yestin Sun **Last Updated:** Fri Sep 10, 2021 07:47 PM UTC **Owner:** nobody **Attachments:** - [openocd_flash_stm32l5_failed_log.txt](https://sourceforge.net/p/openocd/tickets/319/attachment/openocd_flash_stm32l5_failed_log.txt) (612.7 kB; text/plain) I am compiling the openocd from the master branch to try out the flashing on NUCLEO-L552ZE-Q board in secure mode, but find out that there seems to be some regression when flashing in non-secure mode which was working. Here is the error I am getting. Info : device idcode = 0x20016472 (STM32L55/L56xx - Rev 'unknown' : 0x2001) Info : TZEN = 0 : TrustZone disabled by option bytes Info : RDP level 0 (0xAA) Info : flash size = 512kbytes Info : flash mode : dual-bank Info : Padding image section 0 at 0x0800402c with 4 bytes (bank write end alignment) Warn : Adding extra erase range, 0x08004030 .. 0x080047ff Error: timeout waiting for algorithm, a target reset is recommended Error: error executing stm32l4 flash write algorithm Error: flash write failed = 00000088 Error: block write failed Error: error writing to flash at address 0x08000000 at offset 0x00000000 auto erase enabled After some digging, this starts to happen after the switch to C load from the assembly loader. https://review.openocd.org/c/openocd/+/6109 Please also find the debug error log in the attachment.
