Hi everybody, I have some trouble to program my STR9 with my USB Olimix JTAG and OpenOCD (r717) (dev board : E912 Olimex with STR912F44, JTAG : Olimex ARM-USB-OCD, i boot always from bank 0, bank1 is used for data only) I have no problem for debug, everything works perfectly (including FreeRTOS ;-) If I load an image, i can execute, do a reset and continue to use my device. But when i loose my power supply, the software CAN’T restart. Is somebody who have successfully used OpenOCD – Olimex JTAG to burn a STR912 flash ? Is somebody who have already experienced this kind of events. Is it something wrong in my linker file ? Any idea welcome. Thanks in advance.

Hi Damien, I had the same problem on STR912+Eclipse+OpenOCD. I use the same linker file, but I found that the problem was in the startup file – startup.s. I added the following three code lines just before the _start assembly label: -————————————– .text .arm .section .init, "ax" _start:         ldr     pc, =NextInst NextInst: -————————————- This solve my problem by placing the _start function in the right segment. I hope this should help you. Regards, Stefano

Hi Stephano, it’s clear, You have completely right…. Thank you very much for this help Regards.
