Hi,
on my board, LPC1850 is interfaced with S25FL256 over SPIFI. I want to debug my code in S25FL256 using debugger. I am using ULINK2 debugger.
W hen I try to program the external flash (S25FL256) using debugger, I get the following error message :
Flash timeout - Reset the target and try again.
Error: Flash download failed - "Cortex M3"
Please check screenshot of my settings in keil attached here.
I created new flash algorithm for S25FL256 by modifying source code on path c:\Keil\ARM\Flash\LPC18xx43xx_S25FL032. I added following code in FlashDev.c file and created new .FLM file and selected this new flash algorithm in keil setting.
struct FlashDevice const FlashDevice =
{
FLASH_DRV_VERS, // Driver Version, do not modify!
"LPC18xx/43xx S25FL256 SPIFI", // Device Name
EXTSPI, // Device Type
0x14000000, // Device Start Address
0x02000000, // Device Size is 32MB
256, // Programming Page Size
0, // Reserved, must be 0
0xFF, // Initial Content of Erased Memory
500, // Program Page Timeout 100 mSec
5000, // Erase Sector Timeout 3000 mSec
// Specify Size and Address of Sectors
0x001000, 0, // sector size 4 KB (32 sectors)
0x010000,0x20000, // sector size 64 KB (510 sectors)
SECTOR_END
};
I dont understand what is wrong. Can you help me to fix this issue??
Thanks,
