Hi,
I observe a behavior with the QSPI functionality on newer uboot versions; e.g. 2016.11 rc1 and also latest from DENX mainline. I was wondering whether anyone else has experienced similar issue(s) and can perhaps give hints as to what can cause this. I will try to narrow down the issue to a couple of examples related to “sf probe …” and “sf read ..”. I apologize for the long listing, but I am running with full DEBUG for additional details: Example #1: When issuing “sf probe” with no parameters; i.e. use defaults, the command fails and causes board reboot: => sf probe uclass_find_device_by_seq: 0 0 - 0 -1 - not found spi_find_bus_and_cs: No bus 0 uclass_find_device_by_seq: 0 0 - 0 -1 - not found uclass_find_device_by_seq: 1 0 - 0 -1 - found uclass_find_device_by_seq: 0 0 - 0 -1 - not found fdtdec_get_int_array: reg get_prop_check_min_len: reg fdtdec_get_uint: spi-max-frequency: 0x5f5e100 (100000000) fdtdec_get_int: page-size: 0x100 (256) fdtdec_get_int: block-size: 0x10 (16) fdtdec_get_int: tshsl-ns: 0x32 (50) fdtdec_get_int: tsd2d-ns: 0x32 (50) fdtdec_get_int: tchsh-ns: 0x4 (4) fdtdec_get_int: tslch-ns: 0x4 (4) fdtdec_get_int: sram-size: 0x80 (128) cadence_spi_ofdata_to_platdata: regbase=ff705000 ahbbase=ffa00000 max-frequency=100000000 page-size=256 fdtdec_get_int: spi-max-frequency: (not found) spi_get_bus_and_cs: Binding new device 'spi_flash@0:0', busnum=0, cs=0, driver=spi_flash_std Bound device spi_flash@0:0 to spi@ff705000 uclass_find_device_by_seq: 0 -1 uclass_find_device_by_seq: 0 0 - -1 -1 - not found spi_flash_std_probe: slave=7bf49e88, cs=0 cadence_qspi_apb_config_baudrate_div: ref_clk 400000000Hz sclk 1000000Hz Div 0xf cadence_qspi_apb_config_baudrate_div: ref_clk 400000000Hz sclk 100000Hz Div 0xf SF: Read data capture delay calibrated to 7 (0 - 15) cadence_spi_set_speed: speed=100000 cadence_spi_xfer: len=1 [bytes] cadence_qspi_apb_chipselect : chipselect 0 decode 0 cadence_spi_xfer: len=5 [bytes] cadence_qspi_apb_chipselect : chipselect 0 decode 0 SF: Got idcodes 00000000: 20 ba 22 10 44 .".D cadence_spi_xfer: len=1 [bytes] cadence_qspi_apb_chipselect : chipselect 0 decode 0 cadence_spi_xfer: len=1 [bytes] cadence_qspi_apb_chipselect : chipselect 0 decode 0 fdtdec_get_addr_size_fixed: memory-map: (not found) spi_flash_decode_fdt: Cannot decode address SF: Detected MT25QL02 with page size 256 Bytes, erase size 64 KiB, total 256 MiB cadence_qspi_apb_config_baudrate_div: ref_clk 400000000Hz sclk 1000000Hz Div 0xf ### ERROR ### Please RESET the board ### -------------- Example #2: When issuing “sf probe <w/params>”; the command apparently succeeds; i.e. correct flash type is detected.
