用于LPC2000系列芯片的程序烧录 /*Hints on Using the LPC2000 Flash Utility This document can be considered as a supplement to the already existing Application note AN10302 “Using the Philips LPC2000 Flash Utility”, which is provided in the same zip file. The Application note covers the following topics: 1. LPC2000 ISP Overview 2. ISP Mode Entry- Manual and RTS/DTR control circuit 3. Flash and RAM buffer operations 4. Keil MCB2100 board and IAR/Philips 210x KickStart board. Topics discussed in this guide are as follows: 1. Using the “Compare Flash” ISP command. 2. Flashless devices- LPC2220, LPC2210, LPC2290 Using the Compare Flash: The below steps need not be carried out if the checksum is part of the code before it is compiled. This would mean that checksum would be part of the hex file been created. For more detailed information on the checksum calculation please refer to the “Flash Memory System and Programming” chapter in the respective device User Manual. In this case, the hex file can be directly loaded using the “Upload to Flash” button and then the “ Compare Flash” button can be used to compare the Flash contents with the hex file. This direct operation is possible since the signature (or checksum) is part of the hex file already. The below steps need to be carried out if the checksum calculation is not part of the code been compiled. In this case, the checksum calculation has to be done by the utility. Step1: Open the “Buffer” menu and browse to “Flash Buffer operations”. When this menu item is clicked the following window will pop-up. Step2: Now click on the “Load Hex file” button. Please browse to the hex file, which needs to be downloaded into Flash. In this case, Blinky.hex would be loaded. Step3: Select the hex file and press “Open”. This would load the hex file into the buffer window as shown below. Please take a note of location 0x14. In this case, the checksum is not computed before the code is compiled. Step4: Now click on the “Vector Calc” button, which would calculate the checksum and load it at the reserved memory location, 0x14. As shown below this location gets updated. The updated value at 0x14 is as shown below Step5: Since this hex file is modified with the checksum, it needs to be saved back into the same location from where it was loaded. Clicking on the “Save Hex File” button would complete this step. When this is done, a message as shown below should appear. Click “Yes”. Step6: Download the hex file into Flash by clicking on the “Download Flash” button. The progress window should show the progress of the Flash download. Step7: The Flash Buffer Operations window can now be closed. Now, please click here and browse to “Blinky.hex” again. Now click the “Compare Flash” button and it should be a success. Flashless devices- LPC2220, LP2210, LPC2290: Since the LPC2220/2210/2290 does not have on-chip Flash, the ISP utility does not have these devices in its listing of supported Flash devices. However, the utility can still be used to issue ISP commands that would access the on-chip SRAM (using RAM Buffer Operations Window) and bootloader specific ISP commands like Read Device ID. For instance, when the above button is clicked, the ISP utility would complain saying that the “Type is not supported” which basically means that this device is not present in the listing of Flash devices. This error message can be ignored. After “OK” is pressed in the above message, the ISP commands will still be executed and the Part ID and the Boot loader ID will be displayed.*/ /*AN10302 Using the Philips LPC2000 Flash utility with the Keil MCB2100 and IAR LPC210x Kickstart evaluation boards Rev. 03 — 10 June 2004 Application note Document information Info Content Keywords LPC2000, Flash utility, Keil MCB2100, IAR LPC210x Abstract Application information for the Philips LPC2000 Flash utility with the Keil MCB2100 and IAR LPC210x Kickstart evaluation boards 9397 750 13354 © Koninklijke Philips Electronics N.V. 2004.

All rights reserved. Application note Rev. 03 — 10 June 2004 3 of 14 Philips Semiconductors AN10302 Using the Philips LPC2000 Flash utility 1. Introduction In-System programming (ISP) is a method of programming and erasing the on-chip flash or RAM memory using the boot loader software and a serial port. The part may reside in the end-user system. The flash boot loader provides an In-System Programming interface for programming the on-chip flash or RAM memory. This boot loader is located in the upper 8 kB of flash memory, it can be read but not written to or erased. 2. LPC2000 ISP overview The flash boot loader code is executed every time the part is powered on or reset. The loader can execute the ISP command handler or pass execution to the user application code. A LOW level, after reset, at the P0.14 pin is considered as the external hardware request to start the ISP command handler. The boot loader samples this pin during reset. Assuming that proper signal is present on X1 pin when the rising edge on RST pin is generated, it may take up to 3 ms before P0.14 is sampled and the decision on whether to continue with user code or ISP handler is made. If P0.14 is sampled LOW and the watchdog overflow flag is set, the external hardware request to start the ISP command handler is ignored. If there is no request for the ISP command handler execution (P0.14 is sampled HIGH after reset), a search is made for a valid user program. If a valid user program is found then the execution control is transferred to it. If a valid user program is not found, the auto-baud routine is invoked. Pin P0.14 is used as hardware request for ISP requires special attention. Since P0.14 is in high impedance mode after reset, it is important that the user provides external hardware (a pull-up resistor or other device) to put the pin in a defined state. Otherwise unintended entry into ISP mode may occur. Figure 1 shows the boot sequence of the LPC210x devices. 9397 750 13354 © Koninklijke Philips Electronics N.V. 2004. All rights reserved.

Details of the Philips LPC2000 Flash utility This flash utility is available for free download from the Philips website. This software, in combination with the hardware described below, allows for hands-off erasure, uploading, and execution of code. The Philips LPC2000 Flash utility utilizes two, otherwise unused, signals (RTS and DTR) of the PC serial port to control the microcontroller reset and P0.14 pins. The port pin P0.14, if LOW during reset, puts the microcontroller into In System Programming (ISP) mode; this pin has the alternate functions of external interrupt one and general purpose I/O (GPIO). Some details on the associated circuitry will help in understanding how this works. 3.1 Manual entry into ISP mode With jumper J1 removed and jumper J2 in place ISP mode will be entered manually by holding S2 while pressing and releasing S1 (reset). This can become cumbersome and so it is advantageous to use RTS/DTR control of these signals. 3.2 ISP mode entry using DTR/RTS With jumper J1 inserted and jumper J2 removed the reset and P0.14 signals may be controlled by the previously un-used RTS/DTR signals of the PC serial port. In this application both these signals are active HIGH. When RTS is asserted Q2 is turned on and the microcontroller reset is pulled LOW. While the micro is held in reset, DTR is asserted and P0.14 is held LOW. RTS is then brought LOW and so Q2 is turned off. The 10K pull-up resistor releases the RESET signal by pulling it HIGH. The microcontroller is now running in ISP mode. This sequence of ISP mode entry is performed for every operation offered by the Philips LPC2000 Flash Utility. Fig 2.

Application note Rev. 03 — 10 June 2004 6 of 14 Philips Semiconductors AN10302 Using the Philips LPC2000 Flash utility The main screen of the Flash Utility provides access to most if its functionality. When the “use DTR/RTS…” box (1) is checked then control of reset and P0.14 is done by the utility as described above. If this box is unchecked then ISP mode must be entered manually. If the “execute code after upload” is checked then, after code is programmed into the flash, an extra reset pulse is sent to the microcontroller to reset the part. Since, at this time, P0.14 will be HIGH, the part will execute code in flash after this reset. When the utility connects to the MCB2100 it will attempt to connect at the selected baud rate. The highest baud rate achievable will depend mostly on the frequency of the crystal. Using standard baud rate crystals (e.g. 14.7456 MHz) will increase the maximum baud rate achievable. 3.3 Flash buffer operations The flash buffer operation screen (accessible from the “buffer” pull-down menu) allows functions such as loading a HEX file, downloading from flash, uploading to flash, filling the buffer, saving the HEX file and calculation of the checksum “valid code” vector1. There is also the ability to fill the buffer with a particular value1 and program this buffer to flash. Fig 3. Flash Utility main screen. 1. The valid code vector at 0x14 is merely the two’s complement of the sum of the vector table. By assigning it this value the checksum for the entire vector table is 0x00 which indicates valid flash code. After reset the bootloader will examine this location and, if the value is correct (an indication of valid user code in flash), will execute code out of flash. If the value is not correct the bootloader will enter ISP mode. The Philips LPC2000 Flash Utility will automatically calculate and program this value during an upload to flash. Alternatively the vector calculation may be performed on the contents of flash buffer as shown in the screen-shot below. 9397 750 13354 © Koninklijke Philips Electronics N.V. 2004.
