How to, on iMXRT1064 MCU, reset to boot/recovery mode from minicom or Linux terminal (via USB/UART)?

[ernest_yeung_terran]

My colleague, in Windows, was able to connect to a iMXRT1064 MCU via UART and over a terminal at 1200 baud rate send a byte character ("0") to put the MCU into serial downloader boot mode.

When I do the same thing in Linux (i.e. sudo minicom -D /dev/ttyUSB0 -b1200 -S 'send "0"' ) and then try to do a sdphost command, I receive the following error (essentially, I cannot get a ping response back from the MCU):

Preparing to send 82650 (0x142da) bytes to the target.
(1/1)0%getStatusResponse.readPacket error 5.
Status (HAB mode) = 10004 (0x2714) No response from device.

How do I reset the MCU to serial downloader boot mode in Linux? Thanks in advance.

Hi,
Thank you for your interest in NXP Semiconductor products and for the opportunity to serve you.
1) How do I reset the MCU to serial downloader boot mode in Linux?
-- Firstly, I'd like to suggest you check the hardware set and connection, then I'd highly recommend you to use the tool to build the connection with the board after entering the Serial download mode, it's easier than command manipulate.

Have a great day,
TIC

Hi @jeremyzhou just to be sure and crystal clear, can you send the link and the name of this tool in Linux that you mention? (cf. "use the tool to build the connection with the board")
