NXPTM M522XX, KINETIS and i.MX RT / Re: Serial Loader: Placing vars into SDRAM?
« Last post by jackking on February 06, 2024, 01:00:33 AM »OK, that is similar to what I tried, without success.
I set the following in config.h of uTaskerBoot:
I set the following in app_hw_iMX.h of uTaskerSerialBoot:
and added your routine as a menu item under "rd" for RAM DUMP:
Which instantly crashes when trying to write past 0x20 bytes. It also crashes immediately on the read back of the first byte, if I write less than 0x20 bytes.
