Hi everybody!!
I´m using a MQX program with SD driver and a simple shell as a bootloader in a kinetis K60 tower. The idea is to copy firmware from SD to internal flash and run it. To test bootloader I have built two projects, first one a "Hello world" example from kinetis software examples (without mqx) and the second one the MQX "Hello World" example. I change the ICF (IAR linker files) in accordance to "Ethernet Bootloader for MCU" application note. Both examples runs OK when debug.
When I try to jump from (MQX) bootloader to non MQX "hello world" application everything starts OK until the startup code arrives to "Flash_Identify" function where code access to internal flash. Then the processor resets and the bootloader is executed again. Something similar happends when I trying to jump to a MQX application.
I thougth that maybe is necesary to realese some resources in the bootloader before jump. I disbled all interrupts and release some peripherals before jump but the problem remain.
Some ideas?. All advices are wellcome.
