Hi! I tried downloading a new firmware via case SI_BOGUS: - dev_info(&client->dev, "Bogus chip version, trying with no firmware\n"); - fw_name = NULL; + dev_info(&client->dev, "Bogus chip version, trying with new firmware\n"); + fw_name = SI2157_A30_FIRMWARE; break; which I downloaded from + // https://github.com/CoreELEC/dvb-firmware/blob/master/firmware/dvb-tuner-si2157-a30-01.fw resulting in [ 209.312086] si2168 1-0067: downloading firmware from file 'dvb-demod-si2168-b40-01.fw' [ 211.535097] si2168 1-0067: firmware version: B 4.0.25 [ 211.554938] si2157 2-0063: Bogus chip version, trying with new firmware [ 211.554944] si2157 2-0063: found a 'Silicon Labs Si21255-\xff\xff\xff' [ 211.557978] si2157 2-0063: downloading firmware from file 'dvb-tuner-si2157-a30-01.fw' [ 215.739092] si2157 2-0063: rebooting tuner...
