ICE的最高工作頻率是48MHz。(預設為最高工作頻率) 下面是ICEman的help選單 $ ./ICEman.exe -h Usage: ICEman --port start_port_number[:end_port_number] [--help] ICEman --update-fw filename --port, -p: Specific port number to listen connection. --EDM, -E: Specific one EDM version to ICEman. (0x0002 / 0x0010 / 0x0018 / 0x0020 / 0x0030 / 0x0040 / 0x0050) --Mode, -M: SMP\AMP Mode(Default: AMP Mode). --bport, -b: Specific one socket port for communicating with Burner. (default: 2354) --clock, -c: Specific JTAG clock setting 0(30MHz)/1(15MHz)/2(7.5MHz)/ 8(48MHz)/9(24MHz)/10(12MHz) --version, -v: Version of ICEman. --help, -h: The usage is for ICEman. 如果要修改ICE的clock,指令如下 ./ICEman.exe --port 1234 --clock 2 clock 2 表示7.5MHz,其他工作頻率參數如下: 0(30MHz)/1(15MHz)/2(7.5MHz)/8(48MHz)/9(24MHz)/10(12MHz) 實用上,如果ICE用起來怪怪的,可以將ICE降頻試試看。 如果ICE降頻之後可以用,可能是硬體timing的問題,要先解決硬體上的issue。 在AndeSight裡的使用方法如下: Attachment: p1.gif [ 6.52 KiB | Viewed 9108 times ] Attachment: p2.gif [ 10 KiB | Viewed 9108 times ] Attachment: 24M.gif [ 7.73 KiB | Viewed 9087 times ] |
