Hi
A ping fails when debugging AR8035 in the uboot stage.
1. PHY has begun to work correctly, reading the PHY register by the mii command, which is the same as the register of AR8035 chip on Myir company’s development board in terms of reading results.
2. Analog voltage, digital voltage, crystal , RX/TX clock of AR8035 on my boardare the same as Myir’s board.
3. It occasionally succeeds, but fails in most cases when to ping the host computer. When downloading files via TFTP, only one waveform data can be seen in TX/RX. For Myir’s development board, a lot of data pieces can be seen when downloading the same file. What is going on here?
By measuring crystal , both TX/RX clocks are 25MHz. Customer used the latest version of Myir’s SDK.
Thanks.
