HI lilipeeeee
By checking, LPC4357 does not support 64GB SDXC cards. The fix only works for 32GB SDHC.
Sorry for the inconvinience.
Have a nice day,

Thank you for your help!
Hi lilipeeeee,
This link no longer exists.
The bug fix is related an old version lpcopen. lpcopen v3.02 already fixes it.
in sdmmc_18xx_43xx.c there is this:
c_size = prv_get_bits(48, 63, (uint32_t *) g_card_info->card_info.csd) + 1;
To
c_size = prv_get_bits(48, 69, (uint32_t *) g_card_info->card_info.csd) + 1;
32G SD card works well with this fix.
Hope this helps,
Jun Zhang
Thank you for your help
I tested using this software version, but the result was that USB formatting failed and cannot be used
What's your IDE and version?
Which verion of lpcopen works under your IDE?
I tested using the program under this file lpcopen3_02----- "Periph-sdmmc" . still can only recognize 32GB SDHC cards!
I use KeilV5.34 , verion : lpcopen3_02
