One of the problems with the iMX RT series, is that any processor below the 1064 (Teensy 4.0 and 4.1 use 1062) do not have any internal FLASH. It is all external in a separate FLASH chip sitting out there waiting to be read by your competitors. So, the iMXRT has a bunch of boot time complexity, optional encryption, and bootloader memory movement options you have to manage to boot the device. Typical for machines designed to run big OS's, but not normally seen in microprocessors.
Paul Soffrigen, of PJRC, says that some of his bigger customers did not want the ARM SWD exposed, because they thought it would make it easier for competitors to read their object code. Yes, if you tell MCUXpresso to generate a ".hex" file, you can load it with PJRC's separate executable. But I would rather hook a Segger directly to the target. Thanks for the tip about TyQT, I did not know about those tools. --- Graham > > _______________________________________________ time-nuts mailing list -- [email protected] To unsubscribe, go to http://lists.febo.com/mailman/listinfo/time-nuts_lists.febo.com and follow the instructions there.
