Hi geeks ! I am struggling with a strange issue in LPC2368 ISP circuit. I have two different boards of LPC2368 with different layouts.But both of them have same circuit for ISP through UART0 and using FlashMagic for programing. The issue is, the ISP circuit works only on one of the boards.On the ISP non-working board, the processor doesnt respond to the RTS and DTR signals. Whats m...

Hi, I know that many products support ROM upgrade or in system programming (ISP). However, from my brain that logically to enable this feature the mcu should not be locked. So I have a question that whether the above thinking is right ro not. Or if it is right, is it possible to make ISP possible and simultaneously protect our firmware code from being read during verification? Thanks...

A few days ago my ISP blocked my outgoing TCP connections to port 25 - except to their mailserver. After a few calls they agreed to let me also access my domains mailserver (turned out they just allowed it globally to all their customers...). I sometimes use my domains mailserver or my ISP's, but at times, e.g. when I want to have the delivery session to the final recipient mailserver log...

Hi All, I have a strange problem with my board LPC2362. The fresh controller is getting programmed for the very first time. And the second time onwards the controller is not entering into ISP mode. I am using Flash magic for programming. RTS and CTS are included in the ISP connections and using via PC serial port. I have probed the Reset pin and EINT(P2.10). Both are going LOW initially a...

I've been using avr for quite some time now, but recently I encountered a problem programming atmega168 using ISP: set up- JTAG ICE mkII, ISP connector to atmega168 atmega168 uses internal oscillator nothing is connected to the reset pin except for the nSRST of mkII. For the first few tries, programming works fine for a fresh chip. The same code can be programmed to the chip more than on...

Hi!

I'm after a microcontroller with USB ISP right out of the box with support from the micro's regular tools. Important are a small footprint, though preferably not QFN or anything that can't be hand soldered, and that it is relatively cheap. This microcontroller doesn't need a whole lot of grunt, so an 8-bit or 16-bit would be fine. Thanks for your help.

Hi all, I have a very annoying problem: I have an existing design with an ATmega8515, with an ISP connector setup as specified in one of the Atmel appnotes about implementing an ISP connector. It uses a network on the reset line, with a 10k resistor to VCC, a 4n7 cap to ground and a diode across the resistor for protection. This has always worked on a 2313, a 8515 and a Mega8515. I recentl...

Can someone recommend an MCS-51 and AVR programmer? I've seen the etteam mentioned here, but their website seems to be in Thai? Do they sell direct or have a distributor other than Futrelec?

Since it's an ISP programmer (with socket), why couldn'...

Hi, all. My custom board has a LPC2368 installed and runs FreeRTOS. What I am trying to do is to invoke bootloader in ISP mode from my application - to allow in-field firmware upgrade, when FlashMagic tool will be used. I referred the NXP appnote AN10356 to get a clue of how to do it. What I changed in the example given by the appnote, is the use of GPIO pin P0.14, since the silicon use...

Hi I am hoping somone out there may be able to point me in the right direction !! I have a board that has two AT89C51ED2's fitted to it.

We can't use the ATMEL FLIP programer. The hardware is arra...
