Hi,
I need few clarification regarding mmc csd structure declaration. I was taking Atmel mci as reference.
In ProductManualSDCardv2.2.pdf @ page 34 & ProdManualSDCardv1.9[1].pdf @ page 39, says
...
...
...
C_SIZE_MULT 3 bit width
ERASE_BLK_EN 1 bit width
SECTOR_SIZE 7 bit width
WP_GRP_SIZE 7 bit width
WP_GRP_ENABLE 1 bit width
...
...
..
But in mmc.h file inside u-boot-1.3.4\include\asm-avr32\arch-at32ap700x.
Here, inside structure mmc_csd @ line
...
...
...
c_size_mult:3
sector_size:5
erase_grp_size:5
wp_grp_size:5
wp_grp_enable:1
...
...
...
So my doubt is, Shouldn't erase_grp_size come before sector size.
please correct me if i am wrong.
TIA
Regards
Gururaja
