Takeyoshi, Hi, I've been working on the SDMMC driver off and on. I still haven't got it working, but I am making some progress. Here's a log of register reads and writes captured from U-Boot on the SAMA5D27: index usecs op (bytes) register value value binary register long description 0 0 read (4): [0x0040: HTCAPBLT0] 0x27ec0c8c 0010 0111 1110 1100 0000 1100 1000 1100 Host Controller Capabilities 0 Register 1 4983 read (2): [0x00fe:HOST_VERSION] 0x00001502 0000 0000 0000 0000 0001 0101 0000 0010 Host Controller Version Register 2 10101 read (4): [0x0044: HTCAPBLT1] 0x00200f77 0000 0000 0010 0000 0000 1111 0111 0111 Host Controller Capabilities 1 Register 3 15225 write (1): [0x002f: SRR]w 0x00000001 0000 0000 0000 0000 0000 0000 0000 0001 Software Reset Register 4 20428 write (1): [0x0029: PCR]w 0x0000000f 0000 0000 0000 0000 0000 0000 0000 1111 Power Control Register 5 25629 write (4): [0x0034: IRQSTATEN]w 0x027f003b 0000 0010 0111 1111 0000 0000 0011 1011 Interrupt Status Enable Register 6 30833 write (4): [0x0038: IRQSIGEN]w 0x00000000 0000 0000 0000 0000 0000 0000 0000 0000 Interrupt Signal Enable Register 7 44875 read (4): [0x0040: HTCAPBLT0] 0x27e80c8c 0010 0111 1110 1000 0000 1100 1000 1100 Host Controller Capabilities 0 Register 8 49848 read (2): [0x00fe:HOST_VERSION] 0x00001502 0000 0000 0000 0000 0001 0101 0000 0010 Host Controller Version Register 9 54966 read (4): [0x0044: HTCAPBLT1] 0x00200070 0000 0000 0010 0000 0000 0000 0111 0000 Host Controller Capabilities 1 Register 10 60088 write (1): [0x002f: SRR]w 0x00000001 0000 0000 0000 0000 0000 0000 0000 0001 Software Reset Register 11 66296 write (1): [0x0029: PCR]w 0x0000000f 0000 0000 0000 0000 0000 0000 0000 1111 Power Control Register 12 71353 write (4): [0x0034: IRQSTATEN]w 0x027f003b 0000 0010 0111 1111 0000 0000 0011 1011 Interrupt Status Enable Register 13 76557 write (4): [0x0038: IRQSIGEN]w 0x00000000 0000 0000 0000 0000 0000 0000 0000 0000 Interrupt Signal Enable Register 14 88990 read (4): [0x0024: PRSSTAT] 0x01ff0000 0000 0001 1111 1111 0000 0000 0000 0000 Present State Register 15 94080 write (2): [0x002c: SYSCTL]w 0x00000000 0000 0000 0000 0000 0000 0000 0000 0000 System Control Register, or Clock Control Register/Timout Control Register 16 99285 read (1): [0x0028: PROCTL] 0x00000000 0000 0000 0000 0000 0000 0000 0000 0000 Protocol Control Register 17 106408 read (4): [0x0024: PRSSTAT] 0x01ff0000 0000 0001 1111 1111 0000 0000 0000 0000 Present State Register 18 111377 write (2): [0x002c: SYSCTL]w 0x00000000 0000 0000 0000 0000 0000 0000 0000 0000 System Control Register, or Clock Control Register/Timout Control Register 19 116582 read (1): [0x0028: PROCTL] 0x00000000 0000 0000 0000 0000 0000 0000 0000 0000 Protocol Control Register 20 121704 read (4): [0x0024: PRSSTAT] 0x01ff0000 0000 0001 1111 1111 0000 0000 0000 0000 Present State Register 21 126818 write (2): [0x002c: SYSCTL]w 0x00000000 0000 0000 0000 0000 0000 0000 0000 0000 System Control Register, or Clock Control Register/Timout Control Register 22 132150 write (2): [0x002c: SYSCTL]w 0x000057a1 0000 0000 0000 0000 0101 0111 1010 0001 System Control Register, or Clock Control Register/Timout Control Register 23 138235 write (2): [0x002c: SYSCTL]w 0x000057a7 0000 0000 0000 0000 0101 0111 1010 0111 System Control Register, or Clock Control Register/Timout Control Register 24 143292 read (1): [0x0028: PROCTL] 0x00000000 0000 0000 0000 0000 0000 0000 0000 0000 Protocol Control Register 25 148410 write (1): [0x0028: PROCTL]w 0x00000000 0000 0000 0000 0000 0000 0000 0000 0000 Protocol Control Register 26 154620 read (4): [0x0024: PRSSTAT] 0x01ff0000 0000 0001 1111 1111 0000 0000 0000 0000 Present State Register 27 159583 write (4): [0x0030: IRQSTAT]w 0xffffffff 1111 1111 1111 1111 1111 1111 1111 1111 Interrupt Status Register 28 164789 write (4): [0x0008: CMDARG]w 0x00000000 0000 0000 0000 0000 0000 0000 0000 0000 Command Argument Register 29 169993 write (2): [0x000e: CR]w 0x00000000 0000 0000 0000 0000 0000 0000 0000 0000 Command Register 30 175199 read (4): [0x0030: IRQSTAT] 0x00000000 0000 0000 0000 0000 0000 0000 0000 0000 Interrupt Status Register 31 180322 read (4): [0x0010: CMDRSP0] 0x00000000 0000 0000 0000 0000 0000 0000 0000 0000 Command Response 0
I have a MMC sniffer and logic analyzer hooked up and can see traffic on the SD Card bus under U-Boot. Under NuttX, nothing. I am going to try to capture a register log like this one under NuttX, and compare; and maybe try to replay the U-Boot sequence under NuttX to see if I can get signals on the SDMMC bus. If you have more ideas, I would love to hear them. cheers adam On Mon, Apr 13, 2020 at 5:38 PM Adam Feuer <a...@starcat.io> wrote: > Takeyoshi, > > I finally got the new sama5 sam_sdmmc.c driver to compile.
