Hi Alex, --------------------------------------------------------
Override the ONFI timing mode at runtime. Signed-off-by: Alexander Dahl <a...@thorsis.com> --- I used the same board sam9x75-curiosity to test mode 5 😊 I forced in nfc driver the mode 5: + if (conf->timings.sdr.tRC_min < 20000) And I ran the nand torture on 16 MiB: => nand onfi 0 => hsmc decode MCK rate: 270 MHz SMC_SETUP2: 0x00000007 SMC_PULSE2: 0x22112211 SMC_CYCLE2: 0x00220022 SMC_MODE2: 0x001f0003 NCS_RD: setup: 0 (0 ns), pulse: 34 (102 ns), hold: 0 (0 ns), cycle: 34 (102 ns) NRD: setup: 0 (0 ns), pulse: 17 (51 ns), hold: 17 (51 ns), cycle: 34 (102 ns) NCS_WR: setup: 0 (0 ns), pulse: 34 (102 ns), hold: 0 (0 ns), cycle: 34 (102 ns) NWE: setup: 7 (21 ns), pulse: 17 (51 ns), hold: 10 (30 ns), cycle: 34 (102 ns) Standard read applied TDF optimization enabled TDF cycles: 15 (45 ns) Data Bus Width: 8-bit bus NWAIT Mode: 0 Write operation controlled by NWE signal Read operation controlled by NRD signal => time nand torture 0x800000 0x1000000 NAND torture: device 0 offset 0x800000 size 0x1000000 (block size 0x40000) Passed: 64, failed: 0 time: 30.152 seconds => nand onfi 5 => hsmc decode MCK rate: 270 MHz SMC_SETUP2: 0x00000001 SMC_PULSE2: 0x0b060804 SMC_CYCLE2: 0x000b0008 SMC_MODE2: 0x001f0003 NCS_RD: setup: 0 (0 ns), pulse: 11 (33 ns), hold: 0 (0 ns), cycle: 11 (33 ns) NRD: setup: 0 (0 ns), pulse: 6 (18 ns), hold: 5 (15 ns), cycle: 11 (33 ns) NCS_WR: setup: 0 (0 ns), pulse: 8 (24 ns), hold: 0 (0 ns), cycle: 8 (24 ns) NWE: setup: 1 (3 ns), pulse: 4 (12 ns), hold: 3 (9 ns), cycle: 8 (24 ns) Standard read applied TDF optimization enabled TDF cycles: 15 (45 ns) Data Bus Width: 8-bit bus NWAIT Mode: 0 Write operation controlled by NWE signal Read operation controlled by NRD signal => time nand torture 0x800000 0x1000000 NAND torture: device 0 offset 0x800000 size 0x1000000 (block size 0x40000) Passed: 64, failed: 0 time: 15.891 seconds Best regards, Mihai Sain
