3. Programming the LPC90x using PAB90x-1
Once all setups from the previous chapter have been made, using FlashMagic the
LPC90x devices can be programmed in 5 steps corresponding to the numbered
steps on the FlashMagic User Interface.
Step 0.
• Disconnect the power cable from the MCB900 board
• Insert an LPC90x device in EITHER the SO8 socket OR the DIP8 socket of
the PAB90x-1 board. Make sure PIN 1 is aligned correctly.
• Make sure all jumpers are set to "ICP_....".
• Disconnect any cables from J3 and J4 as connected hardware might
interfere with the programming signals.
• Plug the power cable back in to enter ICP mode on the LPC90x (the ICP
mode is only entered on power-up of the MCB900). LED P2.3 on the
MCB900 board should light up.
• Start FlashMagic (Start | Programs | FlashMagic | FlashMagic).
Step 1.
• Select the COM port (make sure it is not already taken by another
application, e.g. some PDA software)
• Select a baud rate of 19200 baud (the ISP-ICP bridge application has a
fixed baud rate of 19200 baud)
• Select the LPC90x device you would like to program (the PAB90x-1 board
can program LPC901, LPC902, and LPC903. (For programming of LPC906
/ LPC907 / LPC908, you need the PAB90x-2 board due to the differences in
pinout.)
