SDIO_INIT_CLK_DIV is 118

SDIO clock frequency is 48MHz / (TRANSFER_CLOCK_DIV + 2)
|
|
SDIO init clock frequency should not exceed 400KHz = 48MHz / (118 + 2)
|

|
|
Default TRANSFER_CLOCK_DIV is 2 (118 / 40)
|
|
Default SDIO clock frequency is 48MHz / (2 + 2) = 12 MHz
|

This might be too fast for stable SDIO operations
|
|
|
|
MKS Robin board seems to have stable SDIO with BusWide 1bit and ClockDiv 8 i.e. 4.8MHz SDIO clock frequency
|
|
Additional testing is required as there are clearly some 4bit initialization problems
