趣味の電子工作と釣りについて。電子工作は、おもに変換器作成。釣りはおもにトラウトの管釣り。
今年のバレンタインデーは中止になりました。これは職場で実際にあった通達（表現は若干違うが、、まぁ。。）で、儀礼的な贈答は禁止するといった社則にのっとって発布された模様。最近はクリスマスも中止続きなので、バレンタインデーよ、お前もか、って感じ。
と、それはともあれ、どうにかHID Bootloaderがビルドできても、これで動くようにアプリを改造するのが結構難しい。いろいろ試行錯誤して、なんとか動くようになった。その方法とは。。。
１．AN1388をよ～く読む
２．そのAPPENDIX C: CONSIDERATIONS WHILE MOVING THE APPLICATION IMAGEを何度も読む。
３．書いてあるとおり、試行錯誤する。
↓↓↓↓↓↓↓↓↓↓↓↓
1.Create a new text file and save it with a .ld file extension.
↓
C:\Microchip Solutions v2012-10-15\USB\Device - CDC - Serial Emulator\PFCMIN-Firmware\MPLAB.X\app.ldというファイルを作成した
2.Add the new *.ld file to your project. The new *.ld file appears in the project tree.
↓
Linker Filesに加えた。ついでにPIC18用のゴミをすべてRemoveした。
3.Starting with the default linker script is easier than starting from the scratch. Use a text editor to copy the contents of the \pic32mx\lib\ldscripts\elf32pic32mx.x default linker script into the newly created *.ld file. The INCLUDE procdefs.ld directive should be replaced with the contents of device specific \pic32mx\lib\proc\device\procdefs.ld portion of the linker script. The path \pic32mx\lib is located inside the folder where C32 compiler tools are installed.
↓
elf32pic32mx.xの内容をすべて、さっき作ったapp.ldに貼り付けする。ついでにprocdefs.ldもapp.ldと同じフォルダーにコピーした。
4.Edit the newly created *.ld file to remap the linker script memory regionsexception_mem,kseg0_boot_mem, kseg1_boot_mem and
↓
ややこしい！結局、app.ldとprocdefs.ldを下記のようにすれば動くはず。あ、もちろんPFCMINとか書いてあるディレクトリ名のところはそのアプリ用に書き換えてね。

と、それはともあれ、どうにかHID Bootloaderがビルドできても、これで動くようにアプリを改造するのが結構難しい。いろいろ試行錯誤して、なんとか動くようになった。その方法とは。。。
１．AN1388をよ～く読む
２．そのAPPENDIX C: CONSIDERATIONS WHILE MOVING THE APPLICATION IMAGEを何度も読む。
３．書いてあるとおり、試行錯誤する。
↓↓↓↓↓↓↓↓↓↓↓↓
1.Create a new text file and save it with a .ld file extension.
↓
C:\Microchip Solutions v2012-10-15\USB\Device - CDC - Serial Emulator\PFCMIN-Firmware\MPLAB.X\app.ldというファイルを作成した
2.Add the new *.ld file to your project. The new *.ld file appears in the project tree.
↓
Linker Filesに加えた。ついでにPIC18用のゴミをすべてRemoveした。
3.Starting with the default linker script is easier than starting from the scratch. Use a text editor to copy the contents of the \pic32mx\lib\ldscripts\elf32pic32mx.x default linker script into the newly created *.ld file. The INCLUDE procdefs.ld directive should be replaced with the contents of device specific \pic32mx\lib\proc\device\procdefs.ld portion of the linker script. The path \pic32mx\lib is located inside the folder where C32 compiler tools are installed.
↓
elf32pic32mx.xの内容をすべて、さっき作ったapp.ldに貼り付けする。ついでにprocdefs.ldもapp.ldと同じフォルダーにコピーした。
4.Edit the newly created *.ld file to remap the linker script memory regionsexception_mem,kseg0_boot_mem, kseg1_boot_mem and
↓
ややこしい！結局、app.ldとprocdefs.ldを下記のようにすれば動くはず。あ、もちろんPFCMINとか書いてあるディレクトリ名のところはそのアプリ用に書き換えてね。
