This is the line of the players based on [[ActionsATJ][ATJ213x]] SoC from actions. Up to day there are E100, E150, E200 and E300 in this family.

|  E100  |  E150  |  E200  |  E300  |

Some basic info gathered so far:
   * [[IriverE100Internals][E100]]
   * [[IriverE150Info][E150]]

Various notes about platform:
There is recovery mode refered as 'ADFU'. Player in this mode accepts custom SCSI commands over usb. This commands allow to load binary blob and execute it (among other things). Uploaded data payload is scrambled with simple XOR based scheme.

<verbatim>
void data_decrypt_xor(uint8_t *data, int32_t len)
{
    const uint8_t key = 0x76; /* lbu $t4, xxxx */
    uint8_t tmp;

    while(len--)
    {
        tmp = *data;   /* lbu   $t0, 9($a0)    */
        tmp -= key;    /* subu  $t1, $t0, $t4  */
        tmp ^= key;    /* xor   $t2, $t1, $t4  */
        tmp += 0x7f;   /* addiu $t0, $t2, 0x7f */ 
        *data = tmp;   /* sb    $t0, 0($a0)    */

        data++;        /* addi  $a0, 1         */
    }
}
