  • Hello All, I need to program an QSPI flash (Macronix MX66L1G45, 128MB) via STM32F769NG, but the available default algorithm of ST_STM32F746G_Disco_QSPI.efi flashloader file doesn´t support this project. According to JLinkDevices.xml it is the correct algorithm for STM32F769NG. Further the pin layout is different to the default on. QSPI_CLK need to be PB2 QSPI_CS need to be PC2 QSPI_D0 need to be PD3 QSPI_D1 need to be PD2 QSPI_D2 need to be PC4 QSPI_D3 need to be PD4 How can I modify the existin…

  • In the meantime I also tried to write some data via the exit steps "write xbit" on a address which is normally used (0x0801D980) but nothing happens. The application code is programmed correctly, also verifiying. --> using Target - "Auto" How can i verify if the write action in the Exit steps was executed??? Regards Stefan

  • Hi Niklas, For my point of view this is not the blocking topic. I use for debugging also a ST-Link and i fully unlock all registers at the test boards. I also use fresh boards from production without anything blocked. But for production programming i will use the J-LINK ARM, when it would work. The option bytes addresses should be somewhere specified as used addresses in the project file, or not?? I tried to use "write 8bit", 16bit and 32bit also in the init steps or exit steps, but it doesnt wo…

  • Hi Niklas, Ah okay I understand the background. I tried to use your mentioned generic way - but unfortunatly without good result. At init steps i add a "Write 16bit" which should write value 0xFFFC to address 0x1FFFC008 (option byte address for this STM32F405xx chip). But it doesnt write the data during auto programming or during some other exectuable actions. I always readback 0xFFFF at specific address. Generally question is when does the programmer execute the inserted "write 16bit"??? Proble…

  • Hello, I need to program a STM32F405RG with using an J-Flash ARM. Unfortunetly i have to use also option bytes, is there a possiblily to use them also on a STM32F405RG?? It seems that J-Flash V5.12e supports only option bytes until STM32F398xx. Please help me, Regards Stefan
