There was a report that one A1004ns device fails to detect its flash chip correctly: [ 1.470297] spi-nor spi0.0: unrecognized JEDEC id bytes: e0 10 0c 40 10 08 [ 1.484110] spi-nor: probe of spi0.0 failed with error -2 It also uses a different flash chip model: * in my hand: Winbond W25Q128FVSIG (SOIC-8) * reported: Macronix MX25L12845EMI-10G (SOP-16) Reducing spi-max-frequency solved the detection failure. Hence revert.
