Failed connecting to i.MX RT1064

Failed connecting to i.MX RT1064. Here's some conditions I've tested.

1. Latest firmware (sam3u2c_if_20210514.hex), Hardware reset in IAR EWARM 9.20.
2. Latest firmware (sam3u2c_if_20210514.hex), Soft reset in IAR EWARM 9.20.
3. Latest firmware (sam3u2c_if_20210514.hex), Soft reset in IAR EWARM 9.20. SWD speed redudced to 1MHz.
4. Latest firmware (sam3u2c_if_20210514.hex), Hardware reset with OpenOCD.
5. Old firmware (sam3u2c_if_20191122.hex), Hardware reset in IAR EWARM 9.20.

The same board could be accessed with Seekfree DAP-Link (which is a low speed DAP-Link).

i.MX RT1064 is a high performance Cortex-M7 MCU from NXP.

I'm able to program and debug a KV58 system (which is also a Cortex-M7 paltform from NXP) with this DAP-Link.

Hope you could do further investigation into this problem. If you need further test result or have a beta firmware,
feel free to contact me. Many Thanks!
