Hi,
We have a Board on LH79525 and using IAR debugger. When we tried to download code using J-Link, we are getting some warning messages as shown below :

Also following are the memory we are usingon our PCB :
External Static Memory – 1Mbytes
Chip selection – nCS1
Start Address = 0x44000044;
End Address = 0x440FFFFF;
External SDRAM - 2MBytes
Chip selection – nSDCS0
Start Address = 0x20000000;
End Address = 0x201FFFFF;
We verified the supply for both RAM and ROM. Also, we are not using any flash loader file (IAR --à Options---à Debugger -à Download – “Use flash loaders” ). If it is required, please suggest us how to create this file for our PCB –LH79525.
Please reply as soon as possible.
Thanks,
Steve
