imxrt1064 in serial downloader mode does not reply

Hello,

I have a imxrt1064 that is configured to boot in serial download mode with a USB cable connected to my PCB. And indeed, I see a HID USB device when I execute "lsusb", just as expected:

Bus 001 Device 058: ID 1fc9:0135 NXP Semiconductors SE Blank RT Family

However, trying to send commands to the device using "blhost" always yields a timeout:

sudo ./blhost --u 0x1FC9,0x0135 -- get-property 1
Inject command 'get-property'
usb hid write, time left = 5000
sendCommandGetResponse.readPacket error 5.
Response status = 10004 (0x2714) No response packet from target device.

The flash does not contain any bootloader at the moment.

Any comment would be much appreciated !

Hi Tamir Michael,

Thank you for your interest in NXP Semiconductor products and
for the opportunity to serve you.
After a brief reviewing of your introduction, I think you miss to download the flashloader image onto the i.MX RT1064 before utilizing the Blhost tool, I've attached an application that guides how to use the flashloader, please refer to it for detail.

Have a great day,
TIC

Hi,

Thanks for your reply.

I guess this link is more relevant to the RT1064:
