Hi,
I'm trying to read and write the e-fuse banks on my iMX27 with Barebox
but still unsuccessfully.
I configured and compiled Barebox with IIM support, so I can see these devices:
barebox:/ ls -l /dev
crw------- 32 imx_iim_bank0
crw------- 32 imx_iim_bank1
crw------- 32 imx_iim_bank2
crw------- 32 imx_iim_bank3
crw------- 32 imx_iim_bank4
crw------- 32 imx_iim_bank5
crw------- 32 imx_iim_bank6
crw------- 32 imx_iim_bank7
and I get:
barebox:/ devinfo
[..]
`---- imx_iim0
`---- 0x00000000-0x0000001f: /dev/imx_iim_bank0
`---- 0x00000000-0x0000001f: /dev/imx_iim_bank1
`---- 0x00000000-0x0000001f: /dev/imx_iim_bank2
`---- 0x00000000-0x0000001f: /dev/imx_iim_bank3
`---- 0x00000000-0x0000001f: /dev/imx_iim_bank4
`---- 0x00000000-0x0000001f: /dev/imx_iim_bank5
`---- 0x00000000-0x0000001f: /dev/imx_iim_bank6
`---- 0x00000000-0x0000001f: /dev/imx_iim_bank7
barebox:/ devinfo imx_iim0
resources:
num : 0
start : 0x10028000
size : 0x00001000
driver: imx_iim
no info available for imx_iim0
Parameters:
permanent_write_enable = 0
explicit_sense_enable = 1
By the way I don't know how to read and write the fuse banks.
If I try to read them, I get:
barebox:/ md -b /dev/imx_iim_bank0
could not parse: /dev/imx_iim_bank0
Can you give me any suggestions on how to proceed with fuses?
Thanks a lot in advance,
Igor.
