3. Flash read and write speed test method¶
a. flash write speed
test method: dd if=/dev/zero of=/dev/mtdblockX bs=1k count=X
b. flash read speed
test method: dd if=/dev/mtdblockX of=/dev/null bs=1k
c. flash write and read
test method: dd if=/dev/mtdblockX of=/dev/mtdblockX bs=1k count=X
Where X is set according to the actual situation
4. FLASH QUAD MODE mechanism¶
The following default state is to first check whether the Flash itself supports Quad Mode. If the Flash itself does not support it, it can only go to Single Read Mode. The corresponding CONFIG is as follows, please use the make menuconfig configuration interface to configure
| Nand | Nor | |
|---|---|---|
| IPL | Default priority to Quad Read Mode | Default priority to Quad Read Mode |
| Uboot | 1. Fast Read Mode: MS_SPINAND_SINGLE_READ=y 2. Quad Mode Read: MS_SPINAND_QUAD_READ=y |
1. Fast_Mode：CONFIG_MS_SPINOR_BURST_READ=y 2. Quad Mode Read: CONFIG_MS_SPINOR_QUAL_READ=y |
| Kernel | 1. Fast_Read_Mode: # CONFIG_NAND_QUAL_READ is not set 2. Quad_Read_Mode: CONFIG_NAND_QUAL_READ=y |
1. Fast_Read_Mode：CONFIG_NOR_SINGLE_READ 2. Quad_Read_Mode: CONFIG_NOR_QUAL_READ |
