If you have questions about specific options let me know.

I have the same issue.

--i2c=xSA,xMA_SZ,xMA,dSZ,[HEX] I2C Read/Write

Is ambiguous to me. So I messed with the command so there were no errors. However, in read or write mode it just returns with a blank line.

Can you give an example?

Actually, looking at the code for sub_app.c it looks like the --i2c option does note write the read data back to the console.

Seems like a bug? ...

case 'R':
rc = sub_i2c_read( fd, config.sa, config.ma, config.ma_sz,
config.buf, config.sz );
break;

1. Regarding --i2c option
--i2c=xSA,xMA_SZ,xMA,dSZ,[HEX] I2C Read/Write

xSA - Slave Address in hexa ( like 51,2E,4D,... )
xMA_SZ - Memory/Register address size bytes in hexa
xMA - Memory/Register address inside slave device in hexa
dSZ - data size decimal
HEX - data to write in hexa like "55 44 3A 5B"

For example:
--i2c=50,2,200,4,"00 01 55 AA" will write 4 bytes to slave 0x50 at address 0x200, address size is 2 bytes.
Transaction corresponds to the following flow:

--i2c=50,2,200,4 will read 4 bytes from slave 0x50 at address 0x200, address size is 2 bytes.
http://www.xdimax.com/sub20/doc/HTML/sub_i2c_read.htm

Regarding dump of the I2C read buffer. It is definitely missing. You can add call to hex_ascii_dump to do it.
We will fix it in next version.
sub_app is mostly reference application to show C coding with SUB-20.
