List of Error Messages

Postby SpaceJelly » Wed Oct 19, 2016 12:55 pm

Hi there,

Is there a list of error messages in the software as we're getting QERR:W30 when trying to write to an SFP+

Thanks!

Hello,

When programmer can't complete operation on the I2C bus, it returns a symbol code of operation, in which process appeared error, and HEX code of error. The MCU generate interrupt and return to software the code of problem. Here most popular codes and reasons of situation:

ERR:WXX or ERR:RXX
Symbol W or R says that problem appeared in progress of Write or Read operation.

Codes of errors

x00 Bus Fail
Critical error of bus line.

x20 - SLA+W+NACK -Programmer sent address byte with write bit and got NACK. Slave didn't answer.

x30 Byte+NACK - Programmer sent the data byte and didn't get a confirmation transfer by Slave.

x38 Collision - Another Master activity on the bus line.

x48 SLA+R+NACK - Programmer sent address byte with read bit and got NACK. Slave didn't answer.

Try to set BPS=80 using command line (under log area) or I2CPAUSE=98
