I use MCUXpresso IDE demo "hello world", and I want to download and debug QSPI Nor flash with jlink V7.94b, but I always get "Break at address "0x20000182" with no debug information available, or outside of program code."
MCUXpresso IDE version: v11.5.1
Nor Flash: IS25LP128F
Jlink version: 7.94
BOOT_MODE[1,0]=10, internal Boot
BOOT_CFG2[3,2,1,0] = 0111
BOOT_CFG1[7~0]=0000,1100
my qspi configuration as below, I have tried to mofify some parameters of qspi flash config, but it did not work,
const flexspi_nor_config_t qspiflash_config = {
.memConfig =
{
.tag = FLEXSPI_CFG_BLK_TAG,
.version = FLEXSPI_CFG_BLK_VERSION,
.readSampleClksrc=kFlexSPIReadSampleClk_LoopbackFromDqsPad,
.csHoldTime = 3u,
.csSetupTime = 3u,
.sflashPadType = kSerialFlash_4Pads,
.serialClkFreq = kFlexSpiSerialClk_100MHz,
.sflashA1Size = 8u * 1024u * 1024u,
.lookupTable =
{
// Read LUTs
FLEXSPI_LUT_SEQ(CMD_SDR, FLEXSPI_1PAD, 0xEB, RADDR_SDR, FLEXSPI_4PAD, 0x18),
FLEXSPI_LUT_SEQ(DUMMY_SDR, FLEXSPI_4PAD, 0x06, READ_SDR, FLEXSPI_4PAD, 0x04),
},
},
.pageSize = 256u,
.sectorSize = 4u * 1024u,
.blockSize = 64u * 1024u,
.isUniformBlockSize = false,
};
I have tried flash driver MIMXRT1050-EVK_IS25WP064A.cfx and MIMXRT1050_SFDP_QSPI.cfx, but got the same issue.
and the logs as attached
Hi @Elsa_7561 ,
Ok, things easy now.
I say the SDRAM, as the memory from 0X80000000 is the SDRAM area, if you don't need it, you don't need to enable it, you can delete it, you also don't need to enable the DCD.
In your previous email, you mentioned this area, this let me think you use the SDRAM, and lack the SDRAM init code.
So now, just delete the memory from 0X80000000:
Then do the debug again.
Don't need the sdram jlinkscript, if you still have question about it, please kindly let me know.
Best Regards,
Kerry
Hi, thanks for your reply. my jlink version is newer than your example, so there is no JLinkDevices.xml file in my local. so I tried another way, I modified the QSPI configuration following your link, and convert the .axf file to create a hex(bin) file, and then open my jflash.exe, select the Nor flash, I could program successfully but the system can not run(I did not get "hello world" from debug port). it looks that I need to do other configuration but I have no idea for this.
Hi, I use our desing board and I do not a EVK demo baord. I could debug and download with "MIMXRT1050_UFL_L0" successfully before. so I think the boot config is OK, BOOT MODE(10, internal boot), BOOT CONFIG(BOOT_CFG2[3~0]=0111, BOOT_CFG1[7~0]=0000,1100). now I upgrade the jlink to version 7.94b, but the bin / hex can not normal run after load. So I use the "hello world" demo, and the same issue. When I debug in MCUXpresso IDE, I always get below error and the code can not stop at main. full log as attached.
Hi @Elsa_7561 ,
So, you still use the RT-UFL?
If yes, please in the MCUXPresso IDE, debug configuration, uncheck the reset before running.
Whether this method works on your side or not?
It is determined by what the flashdriver your are using.
BTW, whether your QSPI flash is the new or not, if it is new, you need to enable the QE bit at first, as I know , the default JLINK flashdriver didn't enable the QE bit.
Wish it helps you!

Hi, with RT-UFL, it does not work directly, I must modify the memory list as below marked RED. if NOT, the RT-UFL does not work either. I do not konw there is any different. Now I want to use the original memory list, because in zephyr system, there is not a location to modify the memory list.
when I use the original memory list, I could see the firmware flash successfully, but it can not normal run, it stopped at HardFault_Handler.
Hi, I checked my local, and I could see a evkbimxrt1050_sdram_init.jlinkscript file in the path evkbimxrt1050_hello_world\.mcuxpressoide_packages_support\MIMXRT1052xxxxB_support\Script.
how could I add the file to my debug configuration? by the way, our board doesn't have external SDRAM....so I am sorry that I am not very clear your point.
In actually, in my case, I want to use zephyr OS, and I could build zephyr demo "hello world" successfully , and I get a zephyr.bin file, but when I load the bin file to target, nothing happen, no print from debug port. it is the same issue as I use demo "hello world" in MCUXpresso IDE(with the orignial memory list). I just accidentally found this problem related to memory list in MCUXpresso IDE. but in zephyr OS, I did not find any location to modify memory list, and it does not use evkbimxrt1050_sdram_init.jlinkscript either. I tried different qspi configuration and then could got different errors (halt at hardfault handle, PC writing error...)

thank you very much! Kerry. thanks for your reminder to delete the SDRAM, After delete the memory list, it works!!! and with the same rule, I also get a print "hello world" in my zephyr OS.
