Dear all,
i am trying to have working this module with kernel 3.10 over
sdio, 4 lines, high speed, on a imx6q.
The bcm43362 CHIP_ID is still missing in kernel 3.10 so i merged
some small parts of 3.14 wifi drivers into 3.10.
Actually, seems this module does not reply to the SDIO probing
commands, i am getting err 110 (time out).
Seems its failing here, into sdio_ops.c
int mmc_send_io_op_cond(struct mmc_host *host, u32 ocr, u32 *rocr)
{
struct mmc_command cmd = {0};
int i, err = 0;
BUG_ON(!host);
cmd.opcode = SD_IO_SEND_OP_COND;
cmd.arg = ocr;
cmd.flags = MMC_RSP_SPI_R4 | MMC_RSP_R4 | MMC_CMD_BCR;
for (i = 100; i; i--) {
>>> err = mmc_wait_for_cmd(host, &cmd, MMC_CMD_RETRIES);
if (err)
break;
I checked trough oscilloscope, the command is sent but the
recognize operation terminates in time out.
I am using device tree. usdhc controller is set as 4 lines SDIO.
Every help or suggestion is appreciated.
Many thanks,
angelo
