evo objašnjenja zbog čega se nemože napraviti upgrade sa CD-a kod Smartvision DS-N820,
FLASH TYPES
(Casimir)
There are 2 different types in the flash routines. If we compare these two H&B 3220 firmwares we can notice differences.
First method is for 16 bits (800) flash used in 8 bit mode. The routine for firmware H&B 01.07 look like this :
ROM:F1F7 Flash_Erase: ; CODE XREF: ROM_F00C+3C_p
ROM:F1F7 mov RAM_3D, R7
ROM:F1F9 clr P3.2 ; Select Flash
ROM:F1FB mov DPTR, #0xAAAA
ROM:F1FE mov A, #0xAA ; ''
ROM:F200
ROM:F200 ROM_F200: ; CODE XREF: ROM_3C04+3C6_j
ROM:F200 movx @DPTR, A
ROM:F201 mov DPTR, #0x5555
ROM:F204 mov A, #0x55 ; 'U'
ROM:F206 movx @DPTR, A
ROM:F207 mov DPTR, #0xAAAA
ROM:F20A mov A, #0x80 ; 'Ç'
ROM:F20C movx @DPTR, A
ROM:F20D mov A, #0xAA ; ''
ROM:F20F movx @DPTR, A
ROM:F210 mov DPTR, #0x5555
ROM:F213 mov A, #0x55 ; 'U'
ROM:F215 movx @DPTR, A
ROM:F216 mov DPTR, #0xAAAA
ROM:F219 mov A, #0x10
ROM:F21B movx @DPTR, A
ROM:F21C clr A
ROM:F21D mov R7, A
Second method is for 8 bits (080) flash. Here is same routine for firmware 03.06 :
ROM:F1F7 Flash_Erase: ; CODE XREF: ROM_F00C+3C_p
ROM:F1F7 mov RAM_3D, R7
ROM:F1F9 clr P3.2 ; Select Flash
ROM:F1FB mov DPTR, #0x5555
ROM:F1FE mov A, #0xAA ; ''
ROM:F200
ROM:F200 ROM_F200: ; CODE XREF: ROM_3B75+3C6_j
ROM:F200 movx @DPTR, A
ROM:F201 mov DPTR, #0x2AAA
ROM:F204 mov A, #0x55 ; 'U'
ROM:F206 movx @DPTR, A
ROM:F207 mov DPTR, #0x5555
ROM:F20A mov A, #0x80 ; 'Ç'
ROM:F20C movx @DPTR, A
ROM:F20D mov A, #0xAA ; ''
ROM:F20F movx @DPTR, A
ROM:F210 mov DPTR, #0x2AAA
ROM:F213 mov A, #0x55 ; 'U'
ROM:F215 movx @DPTR, A
ROM:F216 mov DPTR, #0x5555
ROM:F219 mov A, #0x10
ROM:F21B movx @DPTR, A
ROM:F21C clr A
ROM:F21D mov R7, A
There is only small group of players which are using this second method. From checked 58 different players only 7 use the second method to erase flash memory :
- 05.00.02.02 DAYTEK
- 05.00.02.06 HOMETECH D601
- 05.00.03.05 ELTA 8883A
- 05.00.03.05 HB
- 05.00.03.06 HB
- 05.00.03.06 HU3899
- 05.00.03.06 VERTEX
If a player is flashed with the wrong erase routine, it will not be able to be flash by CD ROM anymore. After pushing "play" the CD open but the player will never reboot, but the player still working after an On/Off (but it will remain on the older firmware).
