Hi Bruce, try to erase the chip once using HighVoltage programming (with the two 10pin-ribbon cables. Then hopefully everything should be fine again with the 6pin cable. The reason for it might be a wrong programming of fuses (to what ever reason). Good luck! regards, Klaus -- Der GMX SmartSurfer hilft bis zu 70% Ihrer Onlinekosten zu sparen!

There are several types of 1200 but they DO NOT have internal oscillators, the same goes for the 90S2313. Only the new Tiny2313 has internal oscillator.

John, > There are several types of 1200 but they DO NOT have internal > oscillators, the same goes for the 90S2313. Only the new Tiny2313 has > internal oscillator. The 1200 did. There was the 1200, shipped with the internal RC oscillator disabled, and the 1200A, with it shipped enabled. Richard --- "Sve je bilo tako tiho a nemirno..." http://www.musicvangogh.com/

I like working with the AVRs, but just do it for fun. Lately, I have been having a problem. When I connect to the AVR Programer, select the Fuses or Lockbits tabs, I get the error: "ISP Mode Error " I have check to make sure that on the Board tab, that the ISP freq is less than 1/4 of the target clock. STK500 Osc = 1.843 MHZ and ISP Freq = 3.998 KHZ. I can actually program the chip, ( AVR 1200 - 12, Also same using 2313 - 10 ). I can not access the Fuses or Lockbits, which I think prevents me from using the internal Oscillator. This use to work. When I select Fuses, all selection are grayed out and have a small red "?" mark. Under Lockbits, "Mode 1 is checked, but has a small red "?", as does mode 2 and 3. Smart Warning and Auto Verify are checked by default. What gives ? Other Facts. This problem was also under AVR 4.x, upgraded to v 4.13. No change. Jumpers Vtarget, Aref, Reset, Xtal 1 are all ON. OscSel set to 2,3. All other jumpers are off. If more info is needed, please ask. Thanks Bruce

Thanks to All, Ok, I under the theory that I may have installed an AVR without internal clocks. AVR 1200. I have now installed AVR 8515. Still same problem. On doing a Highvoltage programming, which I have never done before. I get a failure. The title of the failure is the same. " ISP Mode Error ". Suggest I check that ISP freq in the board page is below 1/4 of clock freq. In the program box at the bottom, it get the following Reading FLASH input file.. OK Entering programming mode.. FAILED! Leaving programming mode..OK! I set the jumper as the STK500 manual stated for HV programming. Vtarget On, AREF Off, Reset On, Xtal1 on, OSCSEL 1&2, I am beginning to think I have a problem in the STK500 board. I think the problem started when I did a upgrade to 4.x and flashed the board. I flashed the board again when I upgraded to 4.13 with no change in the problem. As I have stated, I changed the AVR to 8515. The STK500 programs in ISP Programing mode OK. Just no access to Fuse, LockBits and it would seem, HighVoltage Programming. Bruce

Hi Bruce, in case you have (however) accidently tampered the internal program of your STK500 you may restore that as follows: Disconnect any cables from the two ISP connectors Do not insert any device into the programming sockets Press the programming button just besides the ISP-connector and keep it pressed turn on the Power for the STK500 Release the programming button The STK500 should go into upgrade-mode Now start AVR-Studio (the next steps a have to recover from my memory) Select "Tools" -> "AVRPROG". A device of type 8515 (or 8535 I´m not 100% sure) should be "selected" in the box (you can´t change it anyhow) Select the file stk500.ebn in the following directory: C:\Program Files\Atmel\AVR Tools\STK500 as upgrade file and hit the upgrade/program button. That will write the latest (at least latest according to the version of AVR-Studio you are using) STK500 firmware version to your STK. I just had a similar problem last week and for me that and nothing else was the solution. No idea how I broke the STK. I can´t find the proper document, but I´m sure the above procedure is described much better somewhere in the docs. In general HV-programming should work! One last idea: your power supply is working properly?!? Not too high, not to low in voltage? Good luck! Kind regards, Klaus -- Der GMX SmartSurfer hilft bis zu 70% Ihrer Onlinekosten zu sparen!

Klaus, Ok, I tried what you suggested below. However, it still failed to work. While looking very closely and repeating the procedure several times, I noted on the STK500 Interface box, a selector called " Programming Mode ". Looking closely, I observed that I had the option of selecting PP/HVSP mode. (light bulb goes off in head ) I went back and tried what you suggested for High Voltage programming again, with the PP/HVSP selected. Works Fine now. I did say I never done High Voltage Programming didn't I ? LOL. Also, Noted that the STK500 user guide, pdf, was unclear about the OSCSEL jumper. The picture shows pin 2 & 3 selected. The instructions say pins 1 & 2. I left the pins at 2 & 3 this time. Anyway, Everything is working fine now. Can select Fuses, Lockbits and do high voltage programming. One question. Why did the HV programming fix the problem ? Or is it just one of the mystics of the universe. Just curious. Many Thanks Bruce Klaus Ruebsam wrote:

Correction, Just noted that OSCSEL pins go 3-2-1, and not 1-2-3 as I thought. I had the pins in the correct position the second time, and in the wrong position the first time I tried the HV programming. Bruce Bruce wrote:

Hi Bruce, Good to hear that you are up again. The HV-programming works dofferent to the normal ISP programming. As I´ve never bothered about the differences I´m sorry to say: can´t explain. But as far as I remember, the timing is not depending on any xtal, thus devices "dead" due to wrong programming of oszillator-settings can by "reanimated" (as you succesfully did) by means of HV-programming. Now have fun again with your AVR devices!
