wlink erase --chip ch32v003 --method power-off 00:06:01 [INFO] WCH-Link v2.11 (WCH-LinkE-CH32V305) 00:06:01 [INFO] Erase chip by PowerOff 00:06:01 [ERROR] --chip not specified Error: Chip doesn't support power off erase

Am I missing something?

Could you provide full logs using wlink -vv?

It seems the MCU is not connected.

Probe is not attached to an MCU, or debug is not enabled.

The error message should be fixed.

  1. I checked continuity with a multimeter - everything is fine.
  2. I connected wchlinke to another chip from the same batch, which erased okay with default settings (i.e. without specifying --method), but when I tried to perform erase with power-off - I got the same error.
  3. Last time I had to connect it to a virtualbox windows, which erased it fine with power off through wchlink utility. Now I don't have virtualbox at hand. ;-(

The AttachChip command fails. At least wlink status or wlink regs should work.

thirstyone commented 11 months ago

The problem is the target chip has disabled debug interface (hence I have to erase it via poweroff) - I corrupted it in the very beginning of my firmware code. I am not sure, status or regs would work in that case.

Besides, is AttachChip needed when erasing via poweroff? (I don't see 810d01 command in that case in the log), and the error it returns is "Chip not specified" even when I specify it. Btw, when I use a 'wrong' partnumber, the error is different (see the log above)

fiy: just connected that very chip to wchlink utility on a windowbox, and it erased on power off without any effort. Should I install wireshark?

thirstyone commented 10 months ago

okay. here's what I get from the usb sniffer: 81 0d 01 01 (sent to) 82 0d 04 02 0b 12 00 (received from) 81 0c 02 09 01 (sent to) 82 0c 01 01 (received from) 81 0d 01 0f 09 (sent) 82 0d 01 0f (received)

NB, there is no Attach Chip command before 81 0d 01 01

andelf commented 10 months ago

Thanks. That's helpful.

andelf commented 10 months ago

Could you check the new nightly release?

thirstyone commented 10 months ago

so far so good, it works ;-) however, the chip is not bricked: wlink -vv erase --method power-off --chip ch32v003 10:28:29 [TRACE] (1) wlink::usb_device::libusb: [src/usb_device.rs:118] Device: Bus 250 Device 003: ID 1a86:8010 10:28:29 [DEBUG] (1) wlink::usb_device::libusb: Serial number: "00A48F068577" 10:28:29 [TRACE] (1) wlink::probe: [src/probe.rs:193] send command: GetProbeInfo 10:28:29 [TRACE] (1) wlink::probe: [src/probe.rs:174] send 810d01 01 10:28:29 [TRACE] (1) wlink::probe: [src/probe.rs:184] recv 820d04 020b1200 10:28:29 [INFO] Erase chip by PowerOff 10:28:29 [TRACE] (1) wlink::probe: [src/probe.rs:193] send command: SetSpeed { riscvchip: 9, speed: High } 10:28:29 [TRACE] (1) wlink::probe: [src/probe.rs:174] send 810c02 0901 10:28:29 [TRACE] (1) wlink::probe: [src/probe.rs:184] recv 820c01 01 10:28:29 [TRACE] (1) wlink::probe: [src/probe.rs:193] send command: ByPowerOff(CH32V003) 10:28:29 [TRACE] (1) wlink::probe: [src/probe.rs:174] send 810d02 0f09 10:28:29 [TRACE] (1) wlink::probe: [src/probe.rs:184] recv 820d01 0f

okay. i just bricked it and successfully erased on power off! thank you!
