Hi,
after opening /dev/ad4 with success for O_RDWR, I am getting [EINVAL]
from write(2), which according to man 2 write, means
`` [EINVAL] The pointer associated with d was
negative.'', as you can see below it is not true, I have tried
different block sizes, with same result.
How can I write one byte to /dev/adN ?
1361 ow CALL open(0x80485e3,O_RDWR,<unused>0xbfbfecc8)
1361 ow NAMI "/dev/ad4"
;/dev/ad4 is DOS FAT formatted CF Card.
1361 ow RET open 3
1361 ow CALL write(0x3,0xbfbfecb8,0x8)
1361 ow RET write -1 errno 22 Invalid argument
root@~(0) uname -r
7.0-STABLE
-----------
Best Regards
Lukasz.
