Hello Friends,
I was tried to boot Linux to our TWR-K70F120M Development board. I applied all requirements from your Linux Kinetis BSP Guide for the Freescale TWR-K70F120M Board pdf's . That include(code warrior, elevator modules setup, debugger options, flash operations) etc.
So i prepared Linux System for building u-boot from source code and i can compile u-boot. I successfully flashed to u-boot file to FLASH but problem is when i flashed to u-boot to our development board i see "HARD FAULT exception" on RS232 Serial of elevator serial module
All u-boot prints listed below. I tried prebuild u-boot image too. But same problem occuring. What's is wrong is here?. Is that jumper or hardware fault?. What can i do? Thanks you.
we also get this warning despite having our tower module mt29f2g nand flash.
