Part Number: TDA2EG-17
Other Parts Discussed in Thread: DRA722, PCF8575, PMP
Dear all,
We are a custom board(TDA2EG-17) SDK : Prcceoss vision SDK 0307
my SD card have two partitions (Fat32-boot , ext4-roofs)
and I only modified the DDR in evm.c(by emif execel) and pinmux in mux_data.h(pinmux tool) and dtb
According to our customized board
================================================================================
I want to load Kernel with SD card
I have put some commands in the auto command (ex.mmc rescan and mmc list and mmc info etc...)
But it seems that there is no information about mmc
Finally ran to emmc_android_boot and failed
But I want to use the SD card to boot
What is happening here?
==================Then I took a look at the program=======================
mmc.c
function :mmc_start_init(struct mmc *mmc)
{
.......................
if (mmc_getcd(mmc) == 0 || mmc->cfg->ops->init == NULL)
printf("MMC: no card present\n"); ----------------------------not printed in the log
.......................
}
MMC: no card present\n" is not printed in the log
Does this mean that the sd card is detected?
================================================= This is my log

mmc read addr blk# cnt
mmc write addr blk# cnt
mmc erase blk# cnt
mmc rescan
mmc part - lists available partition on current mmc device
mmc dev [dev] [part] - show or set current mmc device [partition]
mmc list - lists available devices
mmc hwpartition [args...] - does hardware partitioning
arguments (sizes in 512-byte blocks):
[user [enh start cnt] [wrrel {on|off}]] - sets user data area attributes
[gp1|gp2|gp3|gp4 cnt [enh] [wrrel {on|off}]] - general purpose partition
[check|set|complete] - mode, complete set partitioning completed
WARNING: Partitioning is a write-once setting once it is set to complete.
Power cycling is required to initialize partitions after set to complete.
mmc bootbus dev boot_bus_width reset_boot_bus_width boot_mode
- Set the BOOT_BUS_WIDTH field of the specified device
mmc bootpart-resize <dev> <boot part size MB> <RPMB part size MB>
- Change sizes of boot and RPMB partitions of specified device
mmc partconf dev boot_ack boot_partition partition_access
- Change the bits of the PARTITION_CONFIG field of the specified device
mmc rst-function dev value
- Change the RST_n_FUNCTION field of the specified device
WARNING: This is a write-once field and 0 / 1 / 2 are the only valid values.

** First descriptor is NOT a primary desc on 1:1 **
mmc - MMC sub system
Usage:
mmc info - display info of the current MMC device
mmc read addr blk# cnt
mmc write addr blk# cnt
mmc erase blk# cnt
mmc rescan
mmc part - lists available partition on current mmc device
mmc dev [dev] [part] - show or set current mmc device [partition]
mmc list - lists available devices
mmc hwpartition [args...] - does hardware partitioning
arguments (sizes in 512-byte blocks):
[user [enh start cnt] [wrrel {on|off}]] - sets user data area attributes
[gp1|gp2|gp3|gp4 cnt [enh] [wrrel {on|off}]] - general purpose partition
[check|set|complete] - mode, complete set partitioning completed
WARNING: Partitioning is a write-once setting once it is set to complete.
Power cycling is required to initialize partitions after set to complete.
mmc bootbus dev boot_bus_width reset_boot_bus_width boot_mode
- Set the BOOT_BUS_WIDTH field of the specified device
mmc bootpart-resize <dev> <boot part size MB> <RPMB part size MB>
- Change sizes of boot and RPMB partitions of specified device
mmc partconf dev boot_ack boot_partition partition_access
- Change the bits of the PARTITION_CONFIG field of the specified device
mmc rst-function dev value
- Change the RST_n_FUNCTION field of the specified device
WARNING: This is a write-once field and 0 / 1 / 2 are the only valid values.
