Hello, I have a problem programming the flash 28F010. If I use the command "tektool -p example.bin -b 0x1000000 -l 0x180000" they are only programmed the flash from 0x1080000 to 0x1100000 ( bank 2 ) But the curious thing: If I use the command "tektool -p short.bin -b 0x1080000 -l 0x7FFFF" they are programmed the flash from 0x1080000 to 0x1100000 ( bank 2 ) If I use the command "tektool -p short.bin -b 0x1100000 -l 0x7FFFF" they are programmed the flash from 0x1100000 to 0x1180000 ( bank 3 ) The bank 1 not programmed in any case. The command Read and Erase work perfectly. This happens with 2 different flash card and 2 different oscilloscope TDS540. I tried to use 2 different PCI-GPIB National card, but the problem is always the same. it would be possible to solve this problem ? Are there any other tests I can try? Thank you in advance. Sergio |

Hello Sergio, Regarding the special case of 28F010 or further the 28F020, there are two models made respectively by Intel and AMD. Who is manufacturer of your 28F010 ? In case, check attached instructions from madao on length versus flash type. Albert |

Hello Albert, thank you for your interest, I have 2 flash card, one is AMD and one is INTEL and the problem is the same. I have already read all the instructions of madao. The lenght 0x180000 for the 28F010 is correct because before to erase I had the backup and the file matches with firmware found in Internet. The are 12 chip x 128K ( 131072 ) = 1.572Kbyte = 0x180000. |

i haven't clue, why it doesn't write data into flash. Flash program algorithm is same with newer flash on TDS-serie. Difference of amd and intel shouldn't make problem, because: erase , programming and needing of zero filling is excatly same. Only difference between AMD and Intel is quality. (Intel erasing works much faster and less difference by tries of erase on 12 flash ) Sad, i can't check it again on TDS540 /520 anymore, all is already sold. But i can told, i have check with this puplished unified tektool with all flash. (also one unit with mixed amd /intel flash on one firmware-board ) I can check on TDS544A (not much others than TDS540 with 28F020 ), soon (TM) |

Today the tektool program behaved differently: it programmed bank 1 and 2 correctly and bank 3 all FF, perhaps it depends if I switch the oscilloscope off and on again at each command ..... it's strange. Just my curiosity, but during the programming of the cells does not make a check? the program does not give any programming errors. Thank you. |
