Hello,
I'm trying to use this driver on a custom board based on MPC5125 equipped with a
NAND chip TH58NVG5S0FTAK (which should be compatible with MT29F16G08AJADAWP).
Below is my DTS section NFC related:
nfc@40000000 {
compatible = "fsl,vf610-nfc";
#address-cells = <0x1>;
#size-cells = <0x0>;
reg = <0x40000000 0x100000>;
interrupts = <0x6 0x8>;
interrupt-parent = <0x1>;
bank-width = <0x1>;
write-size = <4096>; // Page size
spare-size = <128>; // OOB size
chips = <0x1>;
clocks = <&clks MPC512x_CLK_NFC>;
clock-names = "ipg";
nand@0 {
compatible = "fsl,vf610-nfc-nandcs";
reg = <0>;
nand-bus-width = <8>;
nand-ecc-mode = "hw";
nand-ecc-strength = <32>;
nand-ecc-step-size = <2048>;
nand-on-flash-bbt;
};
};
Just enabling the driver as is I get the following:
[ 0.886396] vf610_nfc 40000000.nfc: Timeout while waiting for BUSY.
[ 0.998378] vf610_nfc 40000000.nfc: Timeout while waiting for BUSY.
[ 1.110378] vf610_nfc 40000000.nfc: Timeout while waiting for BUSY.
[ 1.222378] vf610_nfc 40000000.nfc: Timeout while waiting for BUSY.
[ 1.334381] vf610_nfc 40000000.nfc: Timeout while waiting for BUSY.
[ 1.340590] nand: No NAND device found
Any advice regarding why I get these timeout messages?
Thanks in advance,
Rodolfo
