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.
