ARM mbed on MIMXRT1060-EVKB evaluation board

[mbartel]

I was trying to use the sdphost to communicate with the MIMXRT1060-EVKB evaluation board evaluation board and would get:

Status (HAB mode) = 10004 (0x2714) No response from device.

I was using the VID/PID that I found using lsusb.  I hadn't paid attention to the device string since it indicated it was the NXP device.  But, when I had trouble with the sdphost I realized the string "NXP ARM mbed" may be significant.

I haven't found any information on the mbed being on this evaluation board.  Can I use sdphost to communicate with the board. 

Our design uses i.mx RT1062, do the chips come with the SDP on them or is it mbed now?

Hi @mbartel ,

Please use this command 

sdphost -t 50000 -u 0x1FC9,0x0135 -j -- error-status

What is feedback?

Regards,

Jing

$ ./sdphost -t 50000 -u 0x1FC9,0x0135 -j --debug -- error-status
Error: UsbHidPeripheral() cannot open USB HID device (vid=0x1fc9, pid=0x0135, sn=).

I believe the mbed OS is installed on the evaluation board based on what I see on a Linux box and a Windows box. 

Do I have to have a debugger to clean the board?  I want to communicate with the bootloader that comes on the chip itself.

Plugging into a Window PC, I get a drive mounted with a HTML file available for viewing.  In the Device Manager I see a MBED disk drive, a HID device and a USB Serial port.

Linux lsusb gives: Bus 003 Device 015: ID 0d28:0204 NXP ARM mbed.

Hi @mbartel ,

You inserted the USB cable to a wrong site. Please connect J48. Sdphost/blhost connect to RT1060 boot ROM directly, not via debug probe. Please refer to RT1060-EVKB getting start document.

Jing

Thank you Jing for your help.  That worked.

It wasn't obvious to me from the user manual, so thank you.
