BDT v5.9.5 reading flash issue

wes58

I am using BDT v5.9.5 and TLSR8258. A couple of weeks ago I wrote about this issue with the previous version of BDT - https://forum.telink-semi.cn/forum.php?mod=viewthread&tid=98604&extra=page%3D2 Now with the latest version of BDT the problem is worse. 1. When I try to read flash memory to file via Cmdline Input in BDT: `B85 rf 76000 -s 4k -o "d:\\TelinkIoTStudio\\BDT\\mac_76000.bin"` Flash read is not saved to file and I get the following result in BDT: ``` [08:39:36]: TC32 EVK: Swire ok 1024 byte(s) have finished 2048 byte(s) have finished 3072 byte(s) have finished 4096 byte(s) have finished Save data to bin file error Error<0x1209>: Save data to file error ``` 2. Reading/writing flash memory via "Memory Access" or "Cmdline Input" causing two issues:    When I write to flash memory the data is written to flash but I get this in BDT: ``` [08:52:26]: TC32 EVK: Swire ok Flash status: unlocked 0007f100: ff Write 1 byte(s) at flash address 0x07f100 Error<0x120a>: Read flash directly error ``` Reading the flash doesn't display this error message: ``` [08:52:21]: 1 byte(s) have finished 0007f100: ff [08:52:21]: Total time: 26 ms ``` The second issue is, that the program crashes when reading or writing to Flash of TLSR8258. I modified BDT/config/system.ini's `read\_write\_direct = True` as was suggested in my previous post. This works for TL7218 but not for TLSR8258. In the previous version I only checked with TL7218 and it worked but TLSR8258 didn't work as well - the program crashes. <i class="pstatus"> 本帖最后由 wes58 于 2026-10-8 08:01 编辑 </i><br /> <br />
