lgw_connect:532: INFO: no FPGA detected or version not supported (v0) - version 5.0.1 --Any help #67

Hi Guys i am using the library version 5.0.1 for the lora gateway with the RAK wireless RAK831 lora gateway module. I am using a Linkit 7688 module with the SPI half duplex fix firmware (also only supports 16 byte chunks of payload). I have double checked the pin connection and they seem ok (GND connections, voltage level, and SPI connection are ok )

What i am seeing is this error when i try to do a test_loragw_reg: ./test_loragw_reg Beginning of test for loragw_reg.c Note: SPI port opened and configured ok Note: SPI read success lgw_connect:532: INFO: no FPGA detected or version not supported (v0) Note: SPI read success lgw_connect:555: ERROR: NOT EXPECTED CHIP VERSION (v0) ERROR: CONCENTRATOR UNCONNECTED ERROR: CONCENTRATOR UNCONNECTED ERROR: CONCENTRATOR UNCONNECTED ERROR: CONCENTRATOR UNCONNECTED ERROR: CONCENTRATOR UNCONNECTED IMPLICIT_PAYLOAD_LENGHT = 2003477408 (should be 197) ERROR: CONCENTRATOR UNCONNECTED ERROR: CONCENTRATOR UNCONNECTED FRAME_SYNCH_PEAK2_POS = 2003477408 (should be 11) ERROR: CONCENTRATOR UNCONNECTED ERROR: CONCENTRATOR UNCONNECTED PREAMBLE_SYMB1_NB = 2003477408 (should be 49253) ERROR: CONCENTRATOR UNCONNECTED ERROR: CONCENTRATOR UNCONNECTED ADJUST_MODEM_START_OFFSET_SF12_RDX4 = 2003477408 (should be 3173) ERROR: CONCENTRATOR UNCONNECTED ERROR: CONCENTRATOR UNCONNECTED IF_FREQ_1 = 2003477408 (should be -1947) ERROR: CONCENTRATOR UNCONNECTED ERROR: CONCENTRATOR UNCONNECTED Note: SPI port closed Note: success disconnecting the concentrator End of test for loragw_reg.c

Am i using the wrong version of the library or do i need to change something explicitly in the c/.h files to avoid this error?

Any help would be appreciated.

an test_loragw_spi gives this output: root@mylinkit:~/lora# ./test_loragw_spi Beginning of test for loragw_spi.c Note: SPI port opened and configured ok WARNING: SPI address > 127 Note: SPI write success Note: SPI read success lgw_spi_wb:309: BURST WRITE: to trans 16 # chunk 16 # transferred 16 Note: SPI burst write success lgw_spi_rb:371: BURST READ: to trans 16 # chunk 16 # transferred 16 Note: SPI burst read success lgw_spi_wb:309: BURST WRITE: to trans 2500 # chunk 1024 # transferred -2 lgw_spi_wb:309: BURST WRITE: to trans 1476 # chunk 1024 # transferred -4 lgw_spi_wb:309: BURST WRITE: to trans 452 # chunk 452 # transferred -6 ERROR: SPI BURST WRITE FAILURE lgw_spi_rb:371: BURST READ: to trans 2500 # chunk 1024 # transferred -2 lgw_spi_rb:371: BURST READ: to trans 1476 # chunk 1024 # transferred -4 lgw_spi_rb:371: BURST READ: to trans 452 # chunk 452 # transferred -6 ERROR: SPI BURST READ FAILURE Note: SPI read success data received (simple read): 0 Note: SPI port closed End of test for loragw_spi.c

which is expected given the limitation of the mt7688 chipset (16 bytes paylond chunk only) and the silicon level bug in SPI

Your PCB has no FPGA, so it is normal

Hi Michael,

Hope everything is fine on your side! I have a quick question.

with regard to the duty cycle in EU, US or Korea, there is no calculation to comply with it in packet forwarder right?

And we didn't see it is calculated in Network Server either.

Any hint?
