    Hello to all. The nec adapter is working with upa original and cline. I have old original and upa-s and the board is working fine.

    [QUOTE = tomekdev; 4047426] Мне удалось исправить проблему с "Ошибка захвата скорости передачи". Несмотря на то, что эти 2 или 3 теста завершились неудачно, UPA смог прочитать простую EEPROM (например, ST95160, чтобы проверить, неисправен ли UPA или просто адаптер NEC). Потом выяснилось, что адаптер неисправен из-за содержимого флеш-памяти (ST39SF010A). Несмотря на то, что он не был пустым, это вызывало ошибку скорости передачи. Решение заключалось в том, чтобы прошить опубликованный ранее дамп для 29F010A, независимо от того, что было в ST39SF010A. После этого адаптер работал отлично. В заключение, для исправления адаптера потребовалось внести изменения в плату адаптера, как было опубликовано ранее, и необходимо было перепрограммировать память.

    Надеюсь, это кому-то поможет, с уважением [/ QUOTE]

    The guys wrote that at28c16 is also suitable.

    [QUOTE = PSAcars; 4045998] Всем привет. Никакой томекдев упа не умеет читать и писать SST39SF010A. Для этого вам понадобится TL866A, Виллем или другой программист. Для nec mcu загляните внутрь даташита upas, подключение настраивается на этот программатор. [/ QUOTE]


    there is a cheaper option on ebay-Programmer BIOS PLCC32 (SST39 AT49 PM39 W49 AM29 MX28 MX29 MBM29).I just don't know how he shows himself in his work

    Hello friends, I could not read or write the nec mics with my upa adapter and I had to make the modifications from the first post of my friend PSAcars and flash the SST39SF010A with the dump that our friend PSAcars also shared.
    As soon as I made the modifications the problem was fixed and I was able to read and write a NEC upd780826.


    Thank you so much for sharing it.

    As soon as you flash the mic, the programmer will start working.
