  • [SOLVED] JLink 6.32i will not flash ISSI QSPI flash on LPC4370

    Hi there,

    with the recent versions of JFlash etc. i got that the attached error message occurs quite often. I have to reset the board a few times and find the right timing when the flashing works. Using Ozone or gdb server is no problem as far as i can tell.
    With the 6.32i version is also still the case that the QE Bit in the ISSI qspi is cleared when i reprogram the flash. I another thread about this it was said that there will be a fix soon. Is there already a time when this will happen ?

    Thanks,
    Hans

  • I think a problem in ozone is related to this. When i am attached to a running program i get this error message after a few seconds.

  • Hello,

    Thank you for your inquiry.
    Such an issue is not known to us.
    Are you using custom hardware or an eval board?
    Which SPI Flash are you looking to program exaclty?
    How is the Flash connected to the MCU on your board?

    Best regards,
    Nino

  • Hi,

    i'm using a custom hardware. Its an LPC4370 with an ISSI IS25LP128 QSPI Flash chip. The flash chip is connected through the SPIFI interface of the LPC4370. I'm also sure that earlier versions of JLink worked fine. I'm not exactly which one it is at the moment.

    Best,
    Hans

  • Hello,

    We tried to reproduce the reported issue with an LPC4330-Xplorer eval board an everything was working fine as expected with the latest J-Link software V6.34.

  • ok strange. The Xplorer Evalboard has no ISSI FlashChip as far as i know. I double checked and the newest version have to reset the QE in the ISSI Flash because after i flash it the chip starts in normale spi mode and QSPI mode.

    I should have mentioned to the other problem with the RamCode. When there a programm running on the M0APP_Core and on the M4_Core and i then want to flash the M0_APP core. Only then this error occurs. If there is only a program running on the M4 it works fine.

    I'll check myself with another hardware and i also have an xplorer board which i will try out.
