Long story short I am working on my first commercial product and the lpc17xx series of cortex-m3 processors fits the bill. Picked up this lpc1788 system on ebay for a whopping $47 + $16 = $63 verses the 399.99 it used to cost new. Board appears to power up - comes with JLINK lite for debugging ... Heres a breakdown and pics

Hello
ReplyDeleteDo you know how can I update the firmware in this board? I bought this kit but I didn't receive the J-link lite for arm. Can I save the firmware using USB?
No you cant to my knowledge. the USB host and device interfaces are tied to the lpc1788. there is no ftd2232h on board - which is usually used as a jtag to usb interface.
ReplyDeleteBut you do have the 20 pin ARM JTAG interface. If you can get an olimex usb-tiny you can access the board using JTAG
