AMIC FWH / LPC 49LFXXX can't erase / program

[jowellco]

Anyone can help me erasing / programming AMIC A49LF004TL - firmware hub and AMIC 49LF040TL LPC? I'm using Willem Programmer pcb45b with jumper to pcb3b. Tried the latest software 0.98d12 , even Sivava;s 0.98D11, erasing the chip with no success, the software will just timeout and it cannot be programmed anymore. Hope mpu51 software developer of latest software can add this chip. I'm willing to send the chip to him if necessary. Thanks. Hope ezo can send request to mpu51 to add support for these 2 chips.

0.98d11, 0.98d12 require pcb45 functionality in pcb45 (pcb50) mode. Change both jumpers.
In software select device SST49LF040 or any 4Mb Winbond FWH/LPC device.
Expect get ID reply 0x37 Amic, 0x9D (probably without name)

Hi Ezo,

Thank you for your prompt reply. Tried that, was able to GetID the chip 0x37 - AMIC, and 0x9D without chip name. However, when erasing, it says erase completed by timeout. Blank check fails, as well as programming. Any idea? Could this be a chip support issue of the software? Tried it also with A49LF004TL, GetID works w/ no chip[ name, erase,black check, program error - same results. Hope next sw version can support AMIC fwh / lpc chips. Same programmer works with Winbond / PMC / SST fwh / lpc chips. Thanks.

It's strange. Looks Amic is fully command compatible with SST49LFxxx.
Try get ID, chip erase and blank check
- pcb3b mode, SW 0.97ja, selected SST49LF004, W39V040 and PM49LF004
- pcb45 (pcb50) mode, SW 0.98d12c3, selected SST49LF004, W39V040 and PM49LF004
Vpp jumper for FWH/LPC removed.
Read non-erased chip. Is here any global areas (blocks) erased (0xFF), and areas with content ?
Looking to find chip for tests. mpu51 again disappeared, not replying e-mails.
