PROCESSOR-SDK-AM62X: AM62X : NAND BOOT stopped before kernel loading GPMC driver

Part Number: PROCESSOR-SDK-AM62X
Other Parts Discussed in Thread: TEST2, AM625, SYSCONFIG

Hi Ti experts:

I have a problem on the nand boot . the uboot works ok ,the kernel is also loaded. but it stop before the gpmc conroller .
I have tested 4 situations.
1: SD boot , manual loading the kernel and dtb from sd . the omap-gpmc driver loading ok..there is nand device information. I can nand write the tiboot.bin ,tispl.bin ,u-boot.img and rootfs.ubi to nand parts.
2: SD boot, manual loading the kernel and dtb from the nand part. the omap-gpmc driver loading ok.
3: nand boot, manual loading the kernel and dtb from sd, the kernel is loaded,but it stop before the omap-gpmc c driver loading.
4: nand boot, manual loading the kernel and dtb from nand part, the kernel is loaded,but it stop before the omap-gpmc c driver loading.

below is the nand boot information of .kernel and dtb from the nand-filesystem(ubi file).

why the nand uboot works ok ,but the kernel work not right?what's the problem ?

below it the massage；

how to configure in the uboot for nand boot ? I just find some information on the kerne of nand configuraion.

Hello Helen

The subject matter expert for this currently on travel so you may see some additional delay in responding back

Hello Mukul

I also meet the same problem.

I want to ask, when will the expert return?

Hi Helen,

Can you please debug the kernel GPMC driver (drivers/memory/omap-gpmc.c) to understand if its function gpmc_probe() is ever got called or where it fails before running line 2479 which prints the GPMC version information in the kernel boot log?

2479         dev_info(gpmc->dev, "GPMC revision %d.%d\n", GPMC_REVISION_MAJOR(l),
2480                  GPMC_REVISION_MINOR(l));

Hi Bin

I debuged the kernel GPMC driver (drivers/memory/omap-gpmc.c) and find the dead line.

That is the line "l = gpmc_read_reg(GPMC_REVISION);"

This code is accessing gpmc register, and I made many efford to find why dead here, but nothing is got.

In general，register access is universal, unless the gmpc is not ready, I guess.

Regards

Song

Hi Song,

Do you work on the same project with Helen?

Does this read() never return?

Hi Bin

I don't work on the same project with Helen.

Yes, read() never return, and dead there, even the hardware reset failed !

I press the reset key many times when dead, but no response, failed.

Hi Bin，
I have add #define DEBUG in the kernel GPMC drivers(drives/memory/omap-gpmc.c).but there is not debug information before running line 2479.
I used another solution to solve the problem,it is from the address AM625: Kernel stucked while accessing GPMC revision register during GPMC NAND boot. - Processors forum - Processors - TI E2E support forums. the solution is ：

added gpmc_reset() to do_booti() under cmd/booti.c in uboot.

int do_booti(struct cmd_tbl *cmdtp, int flag, int argc, char *const argv[])
{
int ret;

gpmc_reset();

}

void gpmc_reset(void)
{
u32 regval;

MANGO_DBG_DEFAULT;
regval = gpmc_read_reg(GPMC_SYSCONFIG);
regval |= 0x02;
gpmc_write_reg(GPMC_SYSCONFIG, regval);
}

Now the nand boot works ok .

Hi Helen,

I am glad the issue is resolved with the u-boot patch. Thanks for the update.

Hi Song,

Can you please test if this uboot patch solves the issue for you too?

Hi Bin，

That is stirring message!

I will make a test.

Thank you, and thanks Helen!

Hi Helen,

I add the gpmc reset function in "gpmc_probe()", locate at drivers\memory\ti-gpmc.c

I think that is a good location to place the code.

static int gpmc_probe(struct udevice *dev)
{
struct ti_gpmc *priv = dev_get_priv(dev);
int ret;
struct resource res;

...........................

.......................

priv->capability_flags = dev->driver->of_match->data;
gpmc_capability = priv->capability_flags;

gpmc_reset(); // ^_^ ^_^ ^_^ ^_^ ^_^ ^_^ ^_^ here ^_^ ^_^ ^_^ ^_^ ^_^ ^_^

gpmc_probe_dt_children(dev);

return 0;
}

I test it, it also can resolve the issue.
