IMX8 WILC3000 WiFi driver bringup

love1ymano — Wed, 03 Feb 2021 10:05:21 GMT

Hi,
In our custom board based on IMX8MN, we are facing issue in WILC3000 module WiFi driver bring up.
I'm using linux kernel version 5.4.24-2.1.0+gbabac008e5cf. We are getting below error log for 9 out of 10 times.

Hello,

Please accept my apologies but this is not an NXP module, but you may find it helpful to refer to the following links where similar topics have been discussed:

1. https://community.nxp.com/t5/i-MX-Processors/sdio-probe-timeout-with-wifi-module-on-sdio/m-p/560206

Re: IMX8 WILC3000 WiFi driver bringup

love1ymano — Fri, 19 Feb 2021 05:31:37 GMT

I had tested in two platforms, one is based on IMX6Q SABRESD ARM32(kernel 5.4.70) and the other with custom IMX8MN ARM64 board(kernel 5.4.70), i already tested the ATCWILC3000 driver with IMX6Q SABRESD ARM32 platform with success.

But when i try ATCWILC3000 driver with the IMX8MN ARM64, i got memory problems, when it generate the scatterlist during the CMD53.

I did some changes in probe function for DMA restriction
dma_set_coherent_mask(wilc->dev, DMA_BIT_MASK(32));

Also did some changes in the wilc_sdio_cmd53,

`static int wilc_sdio_cmd53(struct wilc *wilc, struct sdio_cmd53 *cmd)
{
struct sdio_func *func = container_of(wilc->dev, struct sdio_func, dev);
int size, ret;

sdio_claim_host(func);

u8 *temp_data;

temp_data = devm_kzalloc(wilc->dev, cmd->count * cmd->block_size, GFP_KERNEL);
if(!temp_data){
	pr_err("fail to alloc temp data");
}

func->num = cmd->function;
func->cur_blksize = cmd->block_size;
if (cmd->block_mode)
	size = cmd->count * cmd->block_size;
else
	size = cmd->count;

if (cmd->read_write) {  /* write */
	if (cmd->block_mode)
		memcpy(temp_data, cmd->buffer, cmd->count * cmd->block_size);
	else
		memcpy(temp_data, cmd->buffer, cmd->count);
	pr_info("[WRITE]temp_data = %x | cmd->buffer = %x | *temp_data = %x | *cmd->buffer = %x", temp_data,cmd->buffer, *temp_data,*cmd->buffer);

	ret = sdio_memcpy_toio(func, cmd->address,
			       (void *)temp_data, size);
} else {        /* read */
	ret = sdio_memcpy_fromio(func, (void *)temp_data,
				 cmd->address,  size);
	if (cmd->block_mode)
		memcpy(cmd->buffer, temp_data, cmd->count * cmd->block_size);
	else
		memcpy(cmd->buffer, temp_data, cmd->count);
	pr_info("[READ]temp_data = %x | cmd->buffer = %x | *temp_data = %x | *cmd->buffer = %x", temp_data,cmd->buffer, *temp_data,*cmd->buffer);
}
sdio_release_host(func);

if (ret)
	dev_err(&func->dev, "%s..failed, err(%d)\n", __func__,  ret);
kfree(temp_data);
return ret;

Even with these changes I was able to proceed upto some level in WiFi driver initialization, but still it throws some DMA error.

I know it is not an NXP module, but the issue is due to the DMA architecture of IMX8. Since it was working fine with IMX6 platform. Please guide me on this DMA issue.

Hello,

This might be for the number of buffers used for the DMA. Anyway, to isolate the problem, use it without DMA to check if there is a bottleneck in the memory caused by another device using the memory because this seems an overload causing the kernel to stop and not a problem of the DMA itself.

BR,

Ivan.

i Have the same bug, imx8mq with WILC1000 WIFI. Apparently the NXP ADMA isn't reliable, the latest kernel 5.10.23 has some fix on that. You are totally right, is not the module fault, its the NXP IMX8 DMA designed is the problem. And this is just the beginning of IMX8 problems.

Did you manage to fix the problem?

Hi @love1ymano,

I have the exact same problem. Is it possible that you post your solution here?

Best Regards
