hi, thanks!

AS I write some error code into the onchip flash memory of the STR710, I can not set the EIC of this STR710 for ever,it all EIC register is zero. I remove it and replace a new chip,so everything is OK!

I want to know that error code will destory the chip ( I only forget to change the debug address (0x62000000) to the onchip address(0x40000000).

now , I found another problem, when I don't connect my STR710's GND to the earth, my system will be ''dead'', but I connect the GND to the earch,this system will be OK!

In my system, I connect the flash memory on CS0, sram on CS1, LCM module on CS2, my code run on the onchip flash memory, onchip sram, extern flash memory, extern sram.

Could you help me !
