Updating firmware with protected bootloader.

[Firelord]

MCT is now updated and available from http://www.megadrum.info/configtool/

Fixed some minor bugs (featuring the missing 'Max' curve) and created a Java Web Start based installer (just like on the /configtool subsite). Since I don't have access to that subsite I host it on http://www.firelords.net.

Click to install: install.jnlp

It is absolutely safe to remove the above version that I posted in a ZIP archive. Also, whenever the distribution files are changed updates are automatically downloaded and applied.

Also, I just now realized that I had been updating MCT from SVN version 1.82 (1.83 is still not available for checkout). Thus there is no 'Inputs priority' option nor any interface fixes in version 1.84b.

Here is the source code for version 1.84b (also contains NetBeans 6.9 project files etc): http://www.firelords.net/mct/src/mct_1.84b.zip

i am a bit confused about how the encrypted firmware works. Having an encrypted firmware means all the previous versions of the firmware posted on this site is completely useless? There is no way to build a MD or atleast make it functional without ordering the encrypted atmega? Also, what about the PIC for the bootloader? is the bootloader also protected?

i think i read about it a while,Sorry, i am unable to find that specific topic for some reason

thanks

Read it a few times but still didn't get what you meant.

You can use the last unencrypted MegaDrum firmware.

Also, what about the PIC for the bootloader? is the bootloader also protected?

USB firmware for PIC has not changed and is not encrypted.

sorry...actually i dont really understand the encryption stuff myself..lol.. i guess what i m asking is that will be having any problems if i try to build MD using the non-encrypted atmega? i read somewhere that the only disadvantage to using the non-encrypted old version firmware is that i will have to use the programming cable every time for any updates? are there are more disadvantages? Would the programming procedure change? i hope it makes sense


thanks

You need to read this viewtopic.php?f=3&t=1251

Maybe we should add mass storage descriptors to the PIC for multi-platform drag and drop.
Also, if memory serves; the AVR has the SPI pins free ???
