QSPI XiP J-Link programming in MCUXpresso of K82 fails

[deniscollis]

Scenario:

• Kinetis K82
• Micron  MT25TL01GHBB8E12 (Dual QSPI, 2x64MByte)
• MCUXpresso v11.5.0
• Segger J-Link Debug Probe
• Single-Wire (SW) Debug/Programming
• Linker Script /startup/k8x.ld (Unmanaged by MCUXpresso), excerpts below

MEMORY
{
  /* Define each memory region, ensuring each is 4K sector aligned */
  PROGRAM_FLASH (rx) : ORIGIN = 0x00000000, LENGTH = 0x040000 /* 256K bytes (alias Flash)     */
  EXT_PGM_FLASH (rx) : ORIGIN = 0x04000000, LENGTH = 0x060000 /* 384K bytes (alias Flash2)    */
  /*  Note: 0x04000000-0x0405FFFF is XiP alias for 0x68000000-0x6805FFFF  */
  SRAM_LOWER   (rwx) : ORIGIN = 0x1fff0000, LENGTH = 0x010000 /*  64K bytes (alias RAM2)      */
  SRAM_UPPER   (rwx) : ORIGIN = 0x20000000, LENGTH = 0x030000 /* 192K bytes (alias RAM)       */
  /*  Note: 0x68000000-0x6805FFFF reserved for XiP 0x04000000-0x0405FFFF (AKA EXT_PGM_FLASH)    */
}

Debug:

Board programs without error, but I do not notice the 2nd progress bar for flash bank 1 (external SQPI).  When I F8 (Resume) the board runs.  It reads the data from the external flash, but this is all 0xFF (just a white image is displayed)

Help needed:

Any ideas?

Hi @deniscollis , is there any way that you share or give us more details of how and what are you doing? in such a way that we replay your issue and see what are happen.

Are you using a custom board?
