Dear engineer:
Now we are debugging MMCSD FAT on C6748 of MMCSD1(we use the TF card) with JTAG,We encounter the following issues:
MMCSD1 checks card Successfully,but it will hung in "f_mkfs(DRIVE, 0, 0)"????,we changed TF card many times,the result are same.We do not know why???
We have some screenshots about MMCSD1 registers as follows:
1.when connect the JTAG
2.when running" mmcsdStorageInit()",it return success;
3.when ran "checkMediaCard(MMC_INST_ID)",it check TF card successfuuly!!
4. when Executed down,it will hung in "f_mkfs(DRIVE, 0, 0)",we donnot know why???
our gel and code are As shown in Annex.
Looking forward to your reply!!
Best wishes!!
