Willem Programmer Pcb50 Software As A Service Update Hardware ToI bought my Carprog clone 4.01 from digiobd but after about 50 uses starts a counter: 260 uses left update hardware to synchronize and was decreasing, anyway 260 uses is big number to recover the investment (us 209 dlls), the programmer was paid before the counter starts. Thanks: 0 Ok, first we need this stuff: Top Poster Thanked 1 Time in 1 Post 3 Downloads: Uploads: 0 1.- AT91SAM7S256 bin: 2.- Jtag programmer: 3.- Jtag software: We need to prepare the Carprog to connect to Jtag programmer but first the flash need to be erased, the Jtag function in mcu is dissabled, you cant connect to the mcu before erase the flash. Remove the AT88SC eeprom from the board, please note where is the pin 1 in eeprom before remove: Carefully lift the pin 55 (reset) of the mcu and solder a wire and secure it with a small ammount of silicone (you dont want to broke the pin in the process). Connect the Carprog (with the pin 55 dissconected) to the 12v supply, wait about 10 seconds and connect the wire from pin 55 to Vcc (3.3V) in Carprog: 2013-04-08 19:46 Carprog Mcu Reflash Step by step 2 z 12 Wait from 5 to 10 seconds after connect the 12v supply, the flash content will be erased and the Jtag option of the Mcu will be enabled now. Disconnect the 12v supply from carprog and remove the pin 55 wire from vcc. The pin 55 must remain disconnected until the programming process is done. I already made some further tests and the Carprog works well with any version of the software and the COUNTER IS GONE Tested with versions: 3.75, 4.0, 4.1, 4.5, 4.85 and 4.86, the counter never start again. Without jumper the mcu is placed in programming mode: 2013-04-08 19:46 Carprog Mcu Reflash Step by step 8 z 12 Now is probably a waste of time, in the near future will save me some time but from now I can reflash the AT91 in less than 5 minutes. Update: I forgot to mention that I doesnt need to remove the AT88SC eeprom to ERASEREFLASH the AT91 mcu. This is MY OWN experience, so, If you want to do the same, do it at YOUR OWN risk.
