Introduction +---------------- + +This software is used to check the reliability of the link between the host +platform (on which the program is run) and the Lora concentrator register file +that is the interface through which all interaction with the Lora concentrator +happens. + +2. Dependencies +---------------- + +This program only access the Lora gateway HAL library through its loragw_reg +"named registers" access sub-module. + +It was tested with beta8 of the libloragw library, and should be compatible +with any later version of the library and the hardware, assuming the registers +used for the tests are still present. + +The registers used are: +LGW_VERSION +LGW_IMPLICIT_PAYLOAD_LENGHT +LGW_FSK_REF_PATTERN_LSB +LGW_RX_DATA_BUF_ADDR +LGW_RX_DATA_BUF_DATA +A data buffer accessible through the 2 registers above must be implemented. + +3. Usage +--------- + +The tests run forever or until an error is detected. +Press Ctrl+C to stop the application. + +When an error is detected, diagnosis information are displayed. Please refer to +the source code for more details on what is displayed for diagnosis. + +All tests use pseudo-random data generated by the rand() function. The random +generator is not seeded, and the same sequence of data will be use each time the +program is launched. + +Basically, some random data is written, read back and then compared to the +initial written data. Some "useless" read on others registers might be inserted +to be sure that the data read back is coming from the hardware, and not from the +internal buffer(s) of the software driver(s). + +Test 1 > R/W on a simple 8-bit register +Test 2 > R/W on a simple 8-bit register with interstitial reads on VERSION +Test 3 > R/W on a 32-bit register (short SPI bursts access) +Test 4 > data buffer R/W (long SPI bursts access) + +4.
