IMX RT1176 JTAG Debug fail.

[Gyosun]

Hello,

I created a custom board by referring to MIMXRT1170-EVKB.
The differences compared to EVKB are as follows.

MCU : MIMXRT1176DVMAA -> MIMXRT1176CVM8A
Flash : W25Q512NWEIQ -> W25Q128JVEIQ
DDR memory not used.

Unable to enter main() while loading using MCU-LINK-PRO.
I am attaching images captured when it is normal and when it is abnormal.

Thank you.

Hello,

After some more testing, I think I've figured out the cause.

After checking the "Link application to RAM" option, I connected JTAG and succeeded in booting the RAM.

After initializing Flash and reading the Vendor ID, 0xEF was read normally.

However, flexspi_nor_flash_erase_sector and flexspi_nor_flash_page_program do not seem to work properly.

FLASH changed from W25Q512NWEIQ to W25Q128JVEIQ, but things like 4-Byte Address Mode disappeared.

It appears that some commands have disappeared. How do I apply for W25Q128JVEIQ?

Thank you.
Best Regards,
Gyosun.

Hello, my name is Pavel, and I will be supporting your case, the example flexspi_nor_polling us the SFDP is a generic driver that is using to discover the majority of QSPI...

If you want to create your own .cfx maybe this thread could help you.

The other way you may need modify the FCB to correspond to your QSPI, and for that maybe this App note could help you, there is an explanation about the FCB.

Let me know if you have more questions about.

Hi Pavel,

Thank you for your review.

The problem was resolved after modifying
the xif/evkbmimxrt1170_flexspi_nor_config.c file to match the flash used.
part: W25Q128JVEIQ

const flexspi_nor_config_t qspiflash_config = {
.sflashA1Size = 16u * 1024u * 1024u,
[0] = FLEXSPI_LUT_SEQ(CMD_SDR, FLEXSPI_1PAD, 0xEB, RADDR_SDR, FLEXSPI_4PAD, 0x18),
[4 * 5 + 0] = FLEXSPI_LUT_SEQ(CMD_SDR, FLEXSPI_1PAD, 0x20, RADDR_SDR, FLEXSPI_1PAD, 0x18),
[4 * 9 + 0] = FLEXSPI_LUT_SEQ(CMD_SDR, FLEXSPI_1PAD, 0x2, RADDR_SDR, FLEXSPI_1PAD, 0x18),
}

Thank you,
Best Regards,
Gyosun.
