Im very interested of SD2IEC. I there is posted many information about SD2IEC, but I dont speak german.
So may I ask some questions ?
I built SD2IEC 1.2 - I used intructions from www.c64-wiki.com/index.php/SD2IEC. It is easy for me tu build it, but Im not experienced in programming of ATMEGA644P.
Please let me know answers for these questions:
1) When is right time to flash an ATMEGA644P ? When all parts is completely solderd on PBC or when only ATMEGA644P is soldered - I prefer second choice.
2) What program and programmer are good to use ?
For programs I got tips for PonyProg, ISP programmer and myAVR-ProgTool-V139-b2236_en_de (http://shop.myavr.com/index.php?sp=download.sp.php)
For programmers is it possible to use STK200 (I attached schematic of it)
May I use this programmer ? http://www.aliexpress.com/item…t-Win7-64K/817846333.html
3) Is necessary to use bootloader ? Is it possible to flash atmega directly by sd2iec-0.10.3-sw2-m644p.bin ?? In case YES, what fuses do I need to use ? In instructions are fuśes just for flashing of bootloader.
4) For SD2IEC v1.2 is it possible to use sd2iec-0.9.1-LarsP-m644p.bin FIRMWARE ?
Im looking forward for yours tips and answers.
