Boot mode in MIMXRT1024CAG4B

[sowmiya_a]

Hi,

Boot Mode:

We are using MIMXRT1024CAG4B Microcontroller for our design and planned to use the On-Chip Flash for booting by setting the Internal Boot Mode (BOOT_MODE[1:0] = 10b).

• Is there any issue in using the Internal Flash for booting?
• What is the precaution to be taken care in using the Internal Flash from HW and SW perspective?

After first Power On, can we use the JTAG Port or Serial Wire Debug Interface for loading the Program Image into the On-Chip memory?

1. Of course, you can use Internal flash for booting

2. Set BOOT_MODE[1:0] = 10b to enter device boot mode, and also make sure the BT_CFG pins/eFuse 0x450 points to internal NOR Flash, as internal flash is not the only device for booting.

3. Yes, you can load Program image by HW debugger.
