Erase flash, then write program back but fail to running

[Henry586]

Many thanks for such a great tools.

I just read flash from dongle, then erase flash, then write back, but it seems does not run any more. 1) read `D:\tlsr8258\TLSRPGM>TlsrPgm.py -w -t 5 -a 100 -c -pCOM8 -b1000000 rf 0 0x80000 dongle_512k.bin

Is there anything missing? Many thanks!

TLSR8258 Flash memory can be 1 MB. Such chips are usually installed in Tuya's ZTU modules for Zigbee. You can find out the Flash size using the "i" command.

...
Flash JEDEC ID: 0xC86013, Size: 512 kbytes
...

When recording Flash, no full check is performed to speed up the process. If clarification of the record is required, then you should read it again and compare the files. It will take the same amount of time if build in the “verify” command.

that is output of 'i' command: `D:\tlsr8258\TLSRPGM>TlsrPgm.py -s -p com8 i

will try with verify command.

just read out binary file and compare with the original one, found they are same. but the i command return different values as below: `D:\tlsr8258\TLSRPGM>TlsrPgm.py -w -t 5 -a 100 -c -pCOM8 i

The processor is stopped in a different place in the program - therefore there may be different data in the registers...

On the second pass, Flash is not yet enabled. There was no SoC reset. "-t 5" - the reset pulse time of 5 ms is not enough to discharge the capacitor from the programmer pin at 4 mA or pin "reset" is not connected.

[Henry586]

Yes, you are right, only have gnd,sws,pwr connected. Thanks, I will try to modify them and try again.
