Hi,
I am trying to move linux-socfpga from v4.6 to v4.13(or higher) on a propriety
Arria V board and facing following issues with Micron NAND flash
MT29F4G08ABADAWP bring up:
See following error message with linux-socfpga-4.13/4.14-rc2 :
[ 0.654264] nand: device found, Manufacturer ID: 0x00, Chip ID: 0x2c
[ 0.660625] nand: Unknown denali-nand

[ 0.668868] nand: No NAND device found
[ 0.672661] denali-nand-dt: probe of ff900000.nand failed with error -22
See following messages with linux-socfpga -4.12:

[ 0.911647] 0x000018000000-0x000020000000 : "logs"
Also, fail to mount both the partition.
I had added following in our dts:
/* Micron NAND flash MT29F4G08ABADAWP 4Gb (512MB) */
&nand0 {
status = "okay";
compatible = "altr,socfpga-denali-nand";
have-hw-ecc-fixup;
/* Now add our own scheme */
partition@nand0-terraindb {
/* 384MB for terrain database */
label = "terraindb";
reg = <0x00000000 0x18000000>;
};
partition@nand0-logs {
/* 128MB for event & fault logs */
label = "logs";
reg = <0x18000000 0x08000000>;
};
};
Also tried to add following in dts, but no success:
nand-ecc-mode = "hw";
nand-ecc-step-size = <512>;
nand-ecc-strength = <8>;
See following messages with linux-socfpga -4.6 (works fine):
-------------------------
[ 0.649715] denali-nand-dt ff900000.nand: Dump timing register values:

[ 0.720700] 0x000018000000-0x000020000000 : "logs"
And can see that both the partition are mounted properly
/dev/ubi0_0 on /terraindb type ubifs (rw,relatime)
/dev/ubi1_0 on /logs type ubifs (rw,relatime)
Any thoughts on what I am doing wrong or to correct these issues will be very
helpful.
Thanks in advance.
