Hi,

I have been working on a big issue for many hours and I feel like getting crazy.

I am trying to program a STM32F103ZGT6 internal Flash (STM3210E-EVAL board) on a Linux host by using following software:
- the good old GDB
- JLinkGDBServer
- a Segger J-Link (a genuine one ! my company bought it ! Its serial # is 58003380 version 8.0 - The firmware has been updated on last Friday)

After many hours, I have just noticed that the Flash MCU is never programmed when I try to do it through GDB. Same issue when I try to use segger JLinkExe tool directly (in this case, I try to flash a bin file at 0x8000000), thus this is not a GDB issue ! The TM3210E-EVAL.axf file works fine with KEIL IDE but I do not want to use it, I just want to switch to Linux.

My gdb script is:

#
# gdb init file
#

target remote localhost:2331
monitor speed 1000
monitor flash device = STM32ZE
monitor flash download = 1
#monitor reset
#monitor halt
load /home/imaclinux/Téléchargements/STM3210E-EVAL.axf
#load /home/imaclinux/FreeRTOS/Demo/CORTEX_STM32F103E_Eclipse_Linux/RTOSDemo/RTOS$
#monitor loadbin /home/imaclinux/FreeRTOS/Demo/CORTEX_STM32F103E_Eclipse_Linux/RT$
# Initializing PC and stack pointer
# RAM_START_ADDR is at 0x20000000
#monitor reg r13 = (0x20000000)
#monitor reg pc = (0x20000004)
#monitor reg r13 = (0x8000000)
#monitor reg pc = (0x8000004)

I heard of licence for programming the Flash. Do I have to buy such a license in order to be able to program the Flash ??? If so, what do I do with such a license ? Does it allow to download a new firmware in the J-Link ? I have RTFM many times and searched on the Net but did not find out.

Thanks for your help, I am really stuck.
