Issue on NOR flash erase and copy

winstonjacob — Wed, 29 Dec 2021 09:52:29 GMT

We are working on an LS1021A custom board where we are using 2 NOR Flash (IS29GL256-70FLET) chips. We modified our DTS file based on this link https://community.nxp.com/t5/P-Series/cannot-erase-256MB-NOR-flash-beyond-first-139MB/m-p/370821/highlight/true#M1909

&ifc {

#address-cells = <2>;

#size-cells = <1>;

/* NOR Flash on board and SRAM */

ranges = <0x0 0x0 0x0 0x60000000 0x04000000

0x2 0x0 0x0 0x68000000 0x00080000

0x4 0x0 0x0 0x69000000 0x01000000>;

status = "okay";

nor@0,0 {

#address-cells = <1>;

#size-cells = <1>;

compatible = "cfi-flash";

reg = <0x0 0x0 0x2000000

0x1 0x2000000 0x2000000>;

bank-width = <2>;

device-width = <1>;

Our logs look like this

But when we tried to erase using the flash_eraseall command, we are getting the below log

root@atc-gen2:~# flash_eraseall /dev/mtd0
flash_eraseall has been replaced by `flash_erase <mtddev> 0 0`; please use it
Erasing 128 Kibyte @ 0 -- 0 % complete libmtd: error!: MEMERASE64 ioctl failed for eraseblock 0 (mtd0)

We need to know whether our changes are proper for 2 NOR flash chips and also we need solutions to our flash_erase error.

Please check whether you could execute erase and copy command in u-boot.

=> protect off 60000000 +$filesize && erase 60000000 +$filesize && cp.b $load_addr 60000000
$filesize
