06:03 <bobsy> hi

06:04 <bobsy> i have a qualcomm board here with a ipq6010 chipset

06:04 <bobsy> https://wallystech.com/upload/DR6018-Sdatesheet.pdf

06:05 <bobsy> i erased the flash

06:05 <bobsy> is this board supported with openbcd?

06:05 <bobsy> i have a jtag cable here ready to go

06:05 <bobsy> i've never used jtag or openbcd before. any help would be greatly appreciated

06:06 <bobsy> i'm looking for a target config now

06:07 <bobsy> sorry, openocd, my mistake haha

06:24 <bobsy> i tihnk it's actually ipq860x compatible.

06:24 <bobsy> 806*

06:33 <PaulFertser> bobsy: does it have nand flash?

06:34 <PaulFertser> bobsy: you know the target architecture so you can try looking at configs with similar cores.

06:34 <bobsy> PaulFertser, nor i think?

06:34 <PaulFertser> bobsy: I wonder if its controller is compatible with ath79 then :)

06:34 <bobsy> ahh

06:34 <PaulFertser> But unlikely, that was for MIPS targets.

06:35 <bobsy> real life calls, have to go move a truck. be back in a bit

06:35 <bobsy> thanks

06:35 <PaulFertser> Usually the best and easiest way to write to SPI flash is to use a SOIC clamp + flashrom.

06:35 <PaulFertser> Without JTAG

06:53 <bobsy> PaulFertser, ok. what other hardware do i need other than the clamp?

06:54 <bobsy> https://www.amazon.com.au/KeeYees-SOIC8-EEPROM-CH341A-Programmer/dp/B07SHSL9X9/ref=d_pd_vtp_sccl_1_1/357-4618143-4921001?pd_rd_w=otj2m&content-id=amzn1.sym.6c5371fd-e430-44b8-a1bd-99d66b7c7085&pf_rd_p=6c5371fd-e430-44b8-a1bd-99d66b7c7085&pf_rd_r=9735T0HG5FW1DV81WDZ6&pd_rd_wg=xYB3r&pd_rd_r=8bd03e54-6e2f-4349-aa54-55fa16b21caf&pd_rd_i=B07SHSL9X9&psc=1

06:54 <bobsy> will this do?

07:05 <bobsy> well i ordered a kit like that off aliexpress for $2.

08:02 <PaulFertser> bobsy: yes, ch341 should do. Also usually it's possible to use some ft232h-based board (arm olimex jtag adapter and such).

08:03 <PaulFertser> bobsy: sometimes you'd need to find the reset pin on the board to keep CPU off while using the clamp.

08:03 <PaulFertser> See "ISP" page on the flashrom wiki.

08:04 <PaulFertser> bobsy: oh, and btw, each board has its own unique calibration data, usually in this very flash. So if you erased it, and try to use the data from some other board you might violate regulations.

13:29 <LPC122x> Hi, I'm trying to figure out how to make OpenOCD compatible with LPC1226 and LPC1227 MCUs. As far as I got the problem seems to be with the flash driver. If I don't define a flash bank, I can debug, but I would like to program as well. I'm pretty sure the solution lies in src/flash/nor/lpc2000.c but there I am kind of stuck.

13:41 <PaulFertser> LPC122x: hi

13:41 <PaulFertser> LPC122x: have you tried searching Gerrit for related patches already? You can use "message:LPC122" for starters.

13:42 <PaulFertser> LPC122x: if there's no support yet then it should be easy to add provided it's similar enough to other LPC devices.

13:42 <LPC122x> Afraid I don't know what Gerrit is

13:42 <PaulFertser> LPC122x: see e.g. commit b3ed97a4925ff441c3c2679d01e6cdb6edc123d8

13:42 <PaulFertser> LPC122x: https://review.openocd.org

13:44 <LPC122x> Thanks

13:44 <LPC122x> In the meantime I think I've figured out that the only real problem is the auto probing doesn't work

13:44 <LPC122x> If I change the flash definition to this, it seems to work:

13:44 <LPC122x> flash bank $_FLASHNAME lpc2000 0x0 98304 0 0 $_TARGETNAME \

13:44 <LPC122x>  lpc1100 $_CCLK calc_checksum $_IAP_ENTRY

13:45 <PaulFertser> LPC122x: does it actually flash?

13:45 <LPC122x> So basically I hardcoded the flash size and the variant. But I'm just guessing here, would that be an acceptable workaround

13:45 <LPC122x> Yes it seems to flash (only tried it once just now) but extremely slowly

13:45 <PaulFertser> I'd check with the MCU datasheet that sector size matches.

13:45 <LPC122x> 150+ seconds for 32KB

13:46 <PaulFertser> What adapter speed are you using?

13:46 <LPC122x> I don't change anything, I also just found the default seems very low

13:47 <LPC122x> but unsure if I can just increase

13:47 <PaulFertser> You can try increasing, no harm in that.

13:47 <LPC122x> Thanks

13:47 <PaulFertser> You can also check if similar MCUs have reset-init handler which ramps up the frequency after configuring PLL.

13:48 <PaulFertser> Usually you want to try flashing after running "reset init". "program" does that automatically.

13:49 <LPC122x> Thanks for the tips, will look into this

13:50 <PaulFertser> :)

13:53 <LPC122x> Are sector sizes key, or do page sizes count as well? LPC122x has 4k sector with 512 byte pages, but LPC11U3X has 4k sector with 256 byte pages

13:55 <PaulFertser> LPC122x: lpc2000.c mentions sectors but not pages.

13:55 <LPC122x> (y)
