Dear Team,

      

              We are working with BCM4334 with TI-AM335x Microprocessor with Linux-Kernel-3.12, driver related working are completed and when kernel starts we are getting an error "No SDIO Drive strength init done for chip 4334 rev 3 pmurev 17"


We are running the BM4334 module in 3.3 I/O Voltage Level, then we found a patch from web for bcm4334 drive strength,

below mentioned the patch details.


+/* SDIO Drive Strength to sel value table for PMU Rev 17 (1.8v) */

+static const struct sdiod_drive_str sdiod_drvstr_tab6_1v8[] = {

+    {3, 0x3},

+    {2, 0x2},

+    {1, 0x1},

+    {0, 0x0} };

+

+    case SDIOD_DRVSTR_KEY(BCM4334_CHIP_ID, 17):

+         str_tab = sdiod_drvstr_tab6_1v8;

+            str_mask = 0x00001800;

+         str_shift = 11;

+         break;

Whether the mentioned patch is meant for 1.8V volt I/O or the same is ok with 3.3 I/O or else what is the configuration for 3.3 I/O Level.

Regards
