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
