Hi,

there we a few bootloaders written in history - yr.2005 and older.

I have attached , I think, al of them.

1) The first set contains similar approaches but I am not sure they are absolute clear. AN2153, AN2546

2) The bootloader I prefer to port to E128 device is AN3275

Note; the bootloaders 1) use linear format of S19 record so if you have Page_offset format of the S19 record form CodeWarrior you have to transform it to linear format. Bootloader 2) is able to useS19 record directly generated from CodeWarior.

Linear format can be get by means of SreCvt program.

It is really good to study principle of the bootloader and test all routines step by step to understand it and to avoid any mistake.

In addition, only as an example of evolution in the family, I have also attache bootloader for S12P,G,XE devices AN4258.

Best regards,

Ladislav
