Is there any available reference software (MQX or bare board), showing how to compile it for booting from NAND FLASH? The MfgTool for Vybrid features led_sample.bin, which executes well, but I'm not able to compile any custom SW which would run. I explored the Image Vector Table (IVT) of multiple Vybrid A5 MQX programs, compiled under IAR for both IntRam and DDR configurations, and they are all totally different from the expected format, described in chapter 19.6 of the Vybrid Reference Manual, Rev. 7, 06/2014. I tried to modify the .icf file, but without success. (ICF file format description might be useful.)
Just to be clear - I'm able to upload u-boot via MfgTool and flash the binary into the NAND flash, but I'm not able to compile working custom firmware binary.
