AM335x and NAND Flash

Other Parts Discussed in Thread: AM3352

Hello,

We are testing our new board based on am3352 and NAND Flash.

We have made initial porting and up to now we have been able to create a bootable SD with this FW:

- U-Boot 2016.09-rc2

- Kernel 4.4.19 from TI SDK

- Basic Debian GNU/Linux 8 (jessie)

Now we want to load the system and start from NAND. So I have a couple of questions:

1- What is the recommended type of FS to use in order to be as much reliable as possible?

2- How can we create and load this FW to the NAND flash?

Best regards

Hi Angel,

The linked tutorial will be helpful for understanding how to flashing file system to NAND:

Here is one more tutorial:

Hi Tsvetolin,

These links talk about how to use JFFS2.
Looking at more recent discussions it seems that UBIFS is preferred in more recent designs. What do you think?

Could you also help us with this UBIFS?
- Partitions needed to be defined in U-Boot and "board.dts" file in kernel.
- How to create and flash FW to partitions.
- Environment variables in U-Boot to boot.

Best regards
Angel

Angel,

The linked below article will help about creating and flashing UBIFS image to NAND and setting proper u-boot bootargs:

Hi Tsvetolin,

Thanks for your help.

First I have added NAND support in U-Boot, and everything is fine at this point. Then I am trying to configure my .dts file but kernel is not detecting the NAND flash.

I have no changed am33xx.dtsi, so definition for NAND is

gpmc: gpmc@50000000 {

compatible = "ti,am3352-gpmc";

ti,hwmods = "gpmc";

ti,no-idle-on-init;

reg = <0x50000000 0x2000>;

interrupts = <100>;

dmas = <&edma 52 0>;

dma-names = "rxtx";

gpmc,num-cs = <7>;

gpmc,num-waitpins = <2>;

#address-cells = <2>;

#size-cells = <1>;

interrupt-controller;

#interrupt-cells = <2>;

gpio-controller;

#gpio-cells = <2>;

status = "disabled";

};

Then I add NAND configuration in my .dts file

nandflash_pins_default: nandflash_pins_default {

pinctrl-single,pins = <

partition@9 {

};

}; /* NAND@0,0 */

}; /* gpmc */

I attach kernel log so you can see the error.

Any idea on what I am missing or not setting properly?

Best regards

Hello,

Finally I got it running changing configuration in my .dts file. It looks like this now:

&gpmc {
status = "okay";
pinctrl-names = "default";
pinctrl-0 = <&nandflash_pins_default>;
ranges = <0 0 0x08000000 0x40000000>; /* CS0, NAND, 1GB */

nand@0,0 {
compatible = "ti,omap2-nand";
reg = <0 0 4>; /* CS0, offset 0, IO size 4 */
interrupt-parent = <&gpmc>;
interrupts = <0 IRQ_TYPE_NONE>, /* fifoevent */
<1 IRQ_TYPE_NONE>; /* termcount */
rb-gpios = <&gpmc 0 GPIO_ACTIVE_HIGH>; /* gpmc_wait0 */
ti,nand-ecc-opt = "bch16";
ti,elm-id = <&elm>;

Thanks and this issue can be considered closed.

Best regards
