Everything seems fine. When I click DOWNLOAD, output windows says: Load "c:\\Keil\\ARM\\Examples\\Blinky\\Obj\\Blinky.ELF" Erase Done. Programming Done. Verify OK. But when I want to run blinking program in emulator, nothing happens (no blinking). After clicking halt and reset, disassembly window shows: 134: Vectors: LDR PC,Reset_Addr >0x00000000 E59F201C LDR R2,[PC,#0x001C] 135: LDR PC,Undef_Addr 0x00000004 E3A03000 MOV R3,#Vectors(0x00000000) 136: LDR PC,SWI_Addr 0x00000008 E1020093 SWP R0,R3,[R2] 137: LDR PC,PAbt_Addr 0x0000000C E2822028 ADD R2,R2,#SWI_Addr(0x00000028) 138: LDR PC,DAbt_Addr 0x00000010 E1021093 SWP R1,R3,[R2] 139: NOP etc... And when I do one step i emulator, the cursor jumps to adress 0x04 instead of loading 0x1c into PC thus jumping to 0x1c. It seems to me that there is some mess in flash, but I don't have a clue why. I didn't set up anything special in uVision (no memory mapping, no regimes or so), I just have chosen 'ULINK ARM Debugger' instead of 'Use simulator' in 'Flash/Configure Flash tools/Debug' tab. Thank You very much, have a nice day. M. Fiala

Read-Only Author Reinhard Keil Posted 24-Mar-2006 09:20 Toolset ARM	RE: ULINK flashing error Reinhard Keil There are two issues that may cause this: your are using an outdated version of PK-ARM/MDK-ARM. Make sure that you are using the latest version. The serial Flash download mode might be enabled, see: http://www.keil.com/support/docs/2764.htm See also: http://www.keil.com/support/docs/2767.htm http://www.keil.com/support/docs/3030.htm Reinhard

Read-Only Author miroslav fiala Posted 13-Apr-2006 05:00 Toolset ARM	RE: ULINK flashing error miroslav fiala Thanx a lot, it works now. It's been a bug on our board causing it to stay in flashing mode. Thank You again. Mirek
