Hi Erdem,
I'm not actively developing using IMXRT at the moment, but one thing that lead
to problems with debugging was NuttX entering the ARM low-power mode Wait For
Interrupt.
The quick fix is to comment out the following line in
arch/arm/src/imxrt/imxrt_idle.c:
asm("WFI");
Maybe it will help you.
I don't have the user guides at hand, but I suspect J46 and J47, that you
mention, are the jumpers for bypassing the on-board debugger - so you have
overcome that hurdle.

Subject: NuttX on the IMXRT1060-EVK
Hello,
I've been playing with the IMX1060-EVK board for some time. I wanted to test it
by running NuttX on it with networking support enabled.
./tools/configure.sh -l imxrt1060-evk/netnsh
The configurations below have been enabled, referring to the explanation in the
README file.
CONFIG_IMXRT_ENET_PHYINIT=y
CONFIG_IMXRT_GPIO1_0_15_IRQ=y
CONFIG_IMXRT_GPIO_IRQ=y
CONFIG_NETDEV_IOCTL=y
CONFIG_NETDEV_PHY_IOCTL=y
CONFIG_NSH_NETINIT_MONITOR=y
CONFIG_NSH_NETINIT_RETRYMSEC=2000
CONFIG_NSH_NETINIT_SIGNO=18
CONFIG_NSH_NETINIT_THREAD=y
CONFIG_NSH_NETINIT_THREAD_PRIORITY=80
CONFIG_NSH_NETINIT_THREAD_STACKSIZE=1568
In addition to the items above, I also changed the IPv4 address.
CONFIG_NETINIT_IPADDR=0xc0a8b2fa
CONFIG_NETINIT_DRIPADDR=0xc0a8b201
Then, I built the code. Flashed it (via J-Link). The NSH console appears and
works well. Here is the output of 'ifconfig':
eth0 Link encap:Ethernet HWaddr 00:e0:de:ad:be:ef at DOWN
inet addr:192.168.178.250 DRaddr:192.168.178.1 Mask:255.255.255.0
inet6 addr: fc00::2/112
inet6 DRaddr: fc00::1/112
RX: Received Fragment Errors
00000000 00000000 00000000
IPv4 IPv6 ARP Dropped
00000000 00000000 00000000 00000000
TX: Queued Sent Errors Timeouts
00000000 00000000 00000000 00000000
Total Errors: 00000000
The addresses seem fine, but the eth0 interface is DOWN. To bring up eth0, I
use ifup eth0. But this time, the NSH becomes irresponsive, and I have to
perform hard-reset.
I doubted that there was a problem with the hardware. Therefore, I also tried
with the examples (i.e., lwip_httpsrv_freertos) of the MCUXpresso IDE, and
everything worked as expected. I can do step by step debugging with the help of
J-Link and the IDE.
Why I also mentioned J-Link? Because I, too, would like to debug via J-Link to
be able to understand the issue. However, when I try to debug NuttX via J-Link,
the adapter gets disconnected, an I get some weird errors. This is another
story though... (Optimizations suppressed. Debug symbols enabled.)
I spent too much time on it but still haven't come to a solution. Any hints and
tips from the experts on IMXRT platform would be appreciated.
(Here is my setup: Ubuntu 18, Segger J-Link Base, the board is powered through
USB. J46 and J47 are removed. SW7 OFF-OFF-ON-OFF -> QSPI flash is
enabled.)
Best regards,
Erdem
