Hello,
My application works fine when i am running it through RAM, but when I am running it through flash variables in .ebss section are getting corrupted eg. i have one array of size 34 a[34], in application i only use data at locations a[0],a[1],a[2],a[3], but when i start debugger i get garbage data at locations a[5] to a[33] instead of zero. This is the case with all arrays i have defined. is there any problem with linker file? or what could be possible reasons
Please find my linker file below.
