Dear Forum Users,
I've bought a MIMXRT1050-EVK board and started out with the uVision MDK by Keil. I've managed a few simple demos so far but have now inadvertently changed something and they can no longer be downloaded (rebuild works fine). I get the following error:
Load "sdram_debug\\emwin_gui_demo.out" No Algorithm found for: 00000000H - 0000FFFFH No Algorithm found for: 00010000H - 0001E733H Erase skipped! Error: Flash Download failed - "Cortex-M7" Flash Load finished at 17:29:53
I'm using the USB lead to program this board using the CMSIS-DAP debugger which is selected in <options>/<debug>
I've had this example running before but am now lost as to what has changed. I have moved the SW7 settings on the board but they are back as off-on-on-off again - this controls where the board boots from.
The board apparently has different RAM areas: 64MByte Hyperflash 32MByte SDRAM 8MByte QSPI Flash SD Card slot
512kByte onchip SRAM (on the i.MXRT1050 chip).
any pointers would be really appreciated.

Well the zero memory isn't at 0x20000000, so you should probably Uncheck the "Update Target before Debugging" and/or "Load Application at Startup", so it uses the debug script rather than try to Flash the SDRAM/SRAM
Sure there are manuals, documents, examples where things are outlined.
Thank you again for your help - I think I can see where I'm going wrong now.
regards,
