Other Parts Discussed in Thread: AMIC110
Hello,
we are currently using a modified bootloader from the latest TI StarterWare to load the application into RAM.
The board currently boots from SD card.
Unfortunately, it looks like the bootloader (resp. the MMC- or FatFS driver) has a problem if we want to execute the f_write command.
It writes an empty file but with no content and corrupts the FAT file system (file has the correct size but no content).
Therefore I tried to switch to a newer bootloader from the latest SDK/PDK.
I have already added and built my custom board into the PDK structure regarding to your manual:
http://software-dl.ti.com/processor-sdk-rtos/esd/docs/latest/rtos/index_board.html#custom-board-addition
I also tried/changed the files in the starterware sub-directory because in your manual there is only a statement (see 3.1.3.6.2), which says that additional steps have to be done for AM335x, but no discrete manual on how to do this.
1) Is such a manual available?
I would like to rebuild the (secondary) bootloader with my custom board but I have no clue how to do this.
I tried to follow your manual on how to rebuild the bootloader from here:
http://software-dl.ti.com/processor-sdk-rtos/esd/docs/latest/rtos/index_Foundational_Components.html#building-the-bootloader
But it only accepts the EVM values: am335x-evm, am43xx-evm, amic110-ddrless
2) Is there a manual how to change the Make- or Config files to be able to build a bootloader for my custom board?
Thank you,
Markus
