Hello jikang hu,

Please change the Device to NXP SKEAZ64xxx4 to have try .

It seems there is no error in your configuration. I use J-flash v6.20g test , there is no error .

What about your hex file ? How about a simple hex file of bare project ?

And you also can copy&paste this question to Seeger supppot ， there are many cases about J-link:

Alice_Yang：

thanks, i found the problem, because i defined some sectors in SKEAZ_flash.d

i used uint32_t __attribute__((section(".EkeyNum1"))) Ekey1_Num[3] to strorage a global variate, it seems no fault ,even in debug. i looked the .map file, and i found, the Ekey1_Num[3] strorage in 0x1ffff81B, when i download the hex file using j-flash v6.0, the errors come out, so

i modified my code, just used FLASH_Program1LongWord() construction to storage variates in fixed sectors, and didn't divide flash memory,the errors disappared, but i don't know why. can you tell me more details?thanks a lot

Hello Jikang,

I haven't KEAZ64 board, so I test on other KE04 chip, it can work well.

I generate a hex file refer to your requirement, seperate the flash memory , then storage a global variable,

based on KEAZ64xxx4 chip, could you please test it on you side .

My relocate variable code as below :

Hope it helps
