Thanks for your response! When I try the command you suggested, I see the below.
at!partition=?
To print partition table: AT!PARTITION?
To modify partition sizes: AT!PARTITION=<name>,<size0>[,<size1>,...]
<name> - name of the first partition to modify its size, can be blank
<size0> - new size in KB of the first partition
<size1>,... - new sizes of next partitions
for example: AT!PARTITION=0:boot,2560
List of partitions whose size can be modified:
PART BLOCK SIZE
NAME OFFSET (KB)
0:aboot 00000249 1024
0:boot 0000024D 15360
0:system 00000289 30720
0:LEFWKRO 00000301 8960
0:SWIRW 00000324 25600
0:USERAPP 00000388 134144
0:RESERVED 00000594 55808
To disable partition sizes change: AT!PARTITION=disable
OK
So it does look like I can change the partition sizes. Is there any way to recover if I mess up the partitions?
