AM3352关于TLK105网络芯片不通的疑问

6881

问答对人有帮助，内容完整，我也想知道答案 0 各位大牛，这边有两个问题请教下各位： 1、我这边在使用EMAC启动时候无法从网络启动，使用的网络芯片是TLK105，为MII模式，晶振25MHZ，cpu芯片AM3352，cpu晶振24MHz，串口打印信息如下： U-Boot SPL 2013.01.01 (Sep 29 2014 - 10:41:06) Could not probe the EEPROM; something fundamentally wrong on the I2C bus. Could not get board ID. mu*-hdrc: ConfigData=0xde (UTMI-8, dyn FIFOs, bulk combine, bulk split, HB-ISO Rx, HB-ISO Tx, SoftConn) mu-hdrc: MHDRC RTL version 2.0 mu-hdrc: setup fifo_mode 4 mu-hdrc: 28/31 max ep, 16384/16384 memory USB Peripheral mode controller at 47401000 using PIO, IRQ 0 mu-hdrc: ConfigData=0xde (UTMI-8, dyn FIFOs, bulk combine, bulk split, HB-ISO Rx, HB-ISO Tx, SoftConn) mu-hdrc: MHDRC RTL version 2.0 mu-hdrc: setup fifo_mode 4 mu-hdrc: 28/31 max ep, 16384/16384 memory USB Host mode controller at 47401800 using PIO, IRQ 0 Using default environment not set.
