Other Parts Discussed in Thread: TPS65217

hi YaoMing,，

插入sd卡后的板子上出来的串口消息是：

U-Boot SPL 2011.09-00053-g967afe4 (Aug 16 2012 - 15:34:46)
Texas Instruments Revision detection unimplemented
Could not probe the EEPROM; something fundamentally wrong on the I2C bus.
read_eeprom() failure. continuing with ddr3

这个应该是我的tps65217的芯片驱动code没有加进去,请问怎么去改这部分code.

谢谢~

     On the beaglebone there is a eeprom, which stored the board description information.

     The uboot/kernel will read the board description and decide the procedure of the code for difference board including beaglebone.

     On your board, there is no this eeprom and no necessary, so you can just search this code and disable it.

     For the uboot/kernel code, you can refer to the ezsdk.

     For the tps65217 board, you can refer to the code in uboot as board/ti/am335x/evm.c.
