Detail document of register

[littlelid]

I am walking through the code in ./driver/sdr.c, and I encounter some registers and I cannot figure out the meaning of each bit. e.g., the register read by tx_intf_api->TX_INTF_REG_PKT_INFO_read(). Although I notice that there are a few registers that have been explained in the README in ./doc folder, I am wondering where I can get the more detailed explanation of other registers.

You need to figure out the register functionality in this way:

You can find TX_INTF_REG_PKT_INFO_read() in tx_intf.c, where a register address is: TX_INTF_REG_PKT_INFO_ADDR. That address is defined in hw_def.h:

define TX_INTF_REG_PKT_INFO_ADDR (22*4)

This means slv_reg22 in tx_intf.v (in openwifi-hw project). Finally you will find out that this slv_reg22 register reads value from the module tx_status_fifo_i (tx_status_fifo.v). For its meaning, you need to understand the verilog code of the openwifi design.

Currently we don't have such a document yet that describes all registers. We will do it in the future when we believe those registers have become necessary, clean and clear.

Would you please tell me more about you? For example, students? employee? University name or Company name? You could send the information to xianjun.jiao@ugent.be

People could try out the code without telling us, but when people seek help from us we prefer to know who are we helping.

Thanks!

Thank you，I will send the information via mail.
