MIMXRT1010 Boot

christopherjwhi — Tue, 21 Jan 2020 11:28:27 GMT

I have recently bought the MIMXRT1010-EVK and have been playing around with it. I managed to get the SDK Samples loaded and debugger working. However, I now have the board in a state where it will no longer jump to the application; the program counter is stuck in the ROM boot loader section (e.g. 0x20b0cc). I have the Boot switches set to 10, i.e. internal Flex SPI boot mode.

I am new to the crossover processor architecture and I am unsure how to get the board back into a state where I can continue development.

I am developing on a Mac, with MCUXpresso, which complicates matters as a lot of the flashing tools are only available as executables

Any help would be greatly appreciated.

Hello Christopher,

I sent you an email with a step-by-step guide on how to recover your RT1010-EVK.

Have a great day,
Victor

Christopher,

I too had this problem, at the same address; but after uploading my own code, not for any samples. I assume you've moved past the supplied samples too?

My problem was that I hadn't correctly initialised the required boot initialisation tables in Flash. They're set up for the demo examples, but are easy to overwrite if you upload at 0x6000_0000 instead of where they expect you to upload the code at 0x6000_2000. Note that NXP's Boot ROM has control of the processor, so you have to meet their boot requirements as outlined in the i.MX RT1010 Processor Reference Manual (IMXRT1010RM.pdf) Chapter 9, sections 9.1, 9.6.3 and 9.7.

If you want to fully manage the environment like me, you need to have a Flash/FlexSPI Configuration Block (FCB) with Serial NOR Configuration Block at 0x6000_0400-05FF and an Image Vector Table (IVT) at 0x6000_1000-101F.

I wrote my definitions in C++, using the framework that I use for MCUs. I'd be happy to post it, but it makes use of some definitions that I'd have to explain. The trickiest part is the FCB's Look Up Table (LUT): you need to understand the command language of the Flash in use - or just copy the values used by the samples!

import iled_Blinky
set SW8 to 0001 (serial downloader)
run debug to compile and program the board
stop debugger
reboot (power cycle the board)
change SW8 to 0010 (flexspi bood - default mode)
reboot (power cycle the board)
you're done
