Hi U-boot team,
I am looking for u-boot command which can give me flash device specific properties. For example, there should be dedicated commands to get the flash memory size, sector size, page size etc.
Currently I found there is command "sf probe" for spi flash device which is returning device properties into text format as below: SF : Detected N25Q128A with page size 256 Bytes, erase size 64 KiB, total 16 MiB
Similarly I found there is command "nand info" for nand device which is also returning device properties into text format.
These commands ("sf probe" and "nand info") are giving device information in form of message. Which does not meet my requirement.
Actually I would like to integrate u-boot with my tool, where tool will run u-boot command to get the device information. Based on device information tool will react. Here I am looking for some dedicated command which return these property separately. It is difficult to parse the message string to get individual
Let say we includes following commands: "nand info pagesize/sectorsize/size/device" "sf info pagesize/sectorsize/size/device"
for example: "nand info pagesize" command should return page size ( e.g. *256*) "nand info sectorsize" command should return sector size (e.g. *65536* which is 64K) "nand info size" command should return the total size (e.g. *268435456 *which is 16 MB)
Could you please consider this enhancement request in u-boot? Please comment.
What kind of tool? Is it a U-Boot script? How does it get access to the output from U-Boot?
You could use a regular expression to extract the information you need. For the commands you suggest, it might be better to put the values in an environment variable.
