Hi everyone,

 

Now I am checking whether there are problems with Write / Read with various SD cards.

 

As mentioned in the title several cards encountered the following problems.

・Read operation has no problems, But 2nd Write Operation Hangs up.

・"SD_WaitWriteComplete" outputs error "Error: send CMD13 failed with host error 6502"

 

Q. Is there anyone who encountered similar problems?

 

Card Information as follows.

 

card->cid.manufacturerID    = 0x28
card->cid.applicationID     = 16965
card->cid.productName       =
card->cid.productVersion    = 16
card->cid.productSN         = 2600484995
SD_HOST_CLK_FREQ            = 198000000
card->busClock_Hz           = 49500000
card->version               = 8
card->currentTiming         = 1
card->operationVoltage      = 1
card->blockCount            = 31275008
card->blockSize             = 512
card->stat.speedClass       = 0x03
card->stat.uhsSpeedGrade    = 0x00
